JavaScript - Need Help With Debt Calculator Script
I purchased this debt calculator about 6 months ago and thought it was working fine. Turns out that when you enter in 30 for the average interest rate a Warning: Unresponsive Script window pops up and forces you to stop the script. I am very novice to Javascript and tried looking through the code to see if I could find the problem, with no success. I would appreciate it greatly if someone could take a look to see what is wrong. Here is the link to the calculator. http://www.federaldebtreduction.com/calculator.html
Thank You.

Then I would like to be able to add $125 that with is TitleProcess and then $99 to that which is the LicenseFee. Right now I have not been able to get the tax to work on this code. If someone could get this all to work that would be great, or else even if you program your own code.

I have my first ever scholastic JS assignment and so far it's felt nearly impossible to get a grip on how to do it. I've gone through the W3c tutorials entirely 3 times now and still, nothing is clicking mentally. Generally I do better if I can reverse engineer already written code but I can't find anything similar enough to this on the net to figure it out. The assignment is to create a grade averages calculator as seen in this pictu Along with this starter code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Assignments score calculator</title> <style type="text/css"> <!-- .score { width: 30px; } --> </style> </head> <body> <h1>Assignments score calculator</h1> <form id="calculator" name="calculator" method="post" action=""> <p>Enter your Name: <label for="firstname"></label> <br /> <input type="text" name="firstname" id="firstname" /> <p> <label for="A1">Assignment #1 sco </label> <input name="A1" type="text" class="score" id="A1" maxlength="3" /><br /> <label for="A2">Assignment #2 sco </label> <input name="A2" type="text" class="score" id="A2" maxlength="3" /><br /> <label for="A3">Assignment #3 sco </label> <input name="A3" type="text" class="score" id="A3" maxlength="3" /> <p> <label for="button"></label> <input type="submit" name="Submit" id="Submit" value="Submit" xx="doCalculation(this.form.firstname.value,this.form.A1.value,this.form.A2.value,this.form.A3.value)" /> </form> </body> </html> I understand what I need to do, just not the syntax to do it. Any help would be appreciated. Sorry for newbiness. Hello guys, long story short my boss wants me to add this calculator form to our website(here is the link to what he wants exactly) so I try to copy that code but it won't work. I was wondering if this javascript would work. Code: Code: <script language="JavaScript"> function calc() { gear = document.name1.drpPumpType.1; vane = document.name1.drpPumpType.2; if (gear) { txtW = document.form1.txtW.value; txtD = document.form1.txtD.value; txtL = document.form1.txtL.value; int gearCIR; gearCIR = 6 * txtW *(2 * txtD - txtL) * (txtL - txtD) / 2; } else { int vaneCIR; vaneCIR = 12 * txtW * (txtL + txtD) / 4 * (txtL - txtD) / 2; } I probably don't even need a if statement but I haven't program in a long time and never use java script before. so bare with me. here is the html form code Code: Code: <form name="name1"> <table align="center" border="0" width="44%"> <tbody> <tr> <td colspan="3"><span class="BoldHeadingLabel style1">Displacement from Measurements</span></td></tr> <tr> <td width="50"><span class="style1"></span><br /> </td> <td width="157"><span class="BoldLabel style1">Pump/Motor Type:</span></td> <td width="456"> <span class="style1"></span> <br /> </td></tr> <tr> <td width="50"><span class="style1"></span><br /> </td> <td width="157"><span class="BoldLabel style1">Gear Width (W):</span></td> <td><span class="style1"><input name="txtW" id="txtW" maxlength="10" size="10" value="" type="text" /></span></td></tr> <tr> <td width="50"><span class="style1"></span><br /> </td> <td width="157"><span class="BoldLabel style1">Gear Bore Dia.

I copy this code from that website. but can't find any code wrong. I know this code is probably so wrong but any help is much appreciated . I've got this code below, it seems ok, but sometimes, the multiplication does not work..i don't know why... pls help me..thanks btw, this is my 1st javascript "application", so, im really new into this thanks in advance for any help Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html;

I need help trying to figure out how to get my bmi calculator to work. I cant figure out what is wrong with my formula part and why it wont calculate the numbers you type in...pls help! <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <script type="text/javascript"> function calculateBMI() { var weight = numb(document.data.weight.value) var height = numb(document.data.height.value) var height2 = height2 * height2 var BMI = weight * 703 / (height2 * height2) document.form.BodyMassIndex.value=custRound(BMI,1); } </script> <title></title> <style type="text/css"> div.c2 {text-align: center} input.c1 {font-size: 8pt} </style> </head> <body> <div class="c2"> <form name="form" id="form"><input type="text" name="weight" size="4"> Weight (in Kilos) <input type="text" name="height" size="4"> Height (in Centimeters)<br> <br> <input type="text" name="BodyMassIndex" id="BodyMassIndex" size="4"> BMI <input type="button" class="c1" value="Calculate" onclick="calculateBMI()" name="button"> <input type="reset" class="c1" value="Clear Form"></form> </div> </body> </html> I'm decent at JavaScript but I have no idea how I should go about making a calculator. So far I'll drop a bunch of buttons down that all onclick to a function (a,b) and then it will add or w/e then return. How would I incorporate multiple methods such as subtraction or multiplication though? Basically I'm confident I the ability to code or learn to make this calculator, just have no idea how to set this up, thanks. This is what I have so far, but now I am stuck. My instructor wants the output value (Number Set C) to include Number Set A and Number Set B. For instance, if Number Set A is "10" and you want to add Number Set B whose value is also "10", my instructor wants Number Set C to say "10 + 10 = 20". Where am I going wrong, and what is the easiest way I can make this work while making as little changes as possible? Most of the code is what my instructor requires us to use.
