JavaScript - Noob Question - Multiple Scripts?

Hi all, I am a complete novice to pretty much everything internet but have managed to put together a site that I am trying to get off of the ground. Here is the problem that I am having. The first script below is for a script that shows up in my sidebar and is available on every page of my site. The second script is one that I intend to use on only one specific page. Both of the scripts function properly on their own but not when I try to use them as intended. As mentioned in the FAQ, I tried to name all of the variables with unique names but that still does not work. Any suggestions would be greatly appreciated!!

This code is in my sidebar on every page:
Code:

<script type="text/javascript">
<!--

function calculate() {

	var doc = document.pointCalc;
	var points = 0;
	var fiber = doc.fiber.value;
	var fat = doc.fat.value;
	var calories = doc.calories.value;
	points = (calories / 50) + (fat / 12) - (fiber / 5);
	doc.result.value = Math.round(points);
}

// -->

</script>

<center>

<br/>
<br/> 

<div class="storyTitle"><b>Approximate Points Calculator</b></div>
<div class="storyContent">

</tr>

<tr><td colspan="2"><input value="Calculate" onclick="calculate();" type="button"/></td></tr>
<tr><td>POINTS:</td><td><input name="result" type="text"/></td></tr>

</form>
</div></center>

This code I'm trying to use on just one page of the site:
Code:

<center><script type="text/javascript">
<!--

function getpoints() {

	var doc1 = document.pointquiz;
	var dpoints = 0;
	var sex = doc1.sex.value;
	var age = doc1.age.value;
	var weight = doc1.weight.value;
	var height = doc1.height.value;
	var activity = doc1.activity.value;
	var nursing = doc1.nursing.value;

	dpoints = (sex * 1) + (age * 1) + (weight * 1) + (height * 1) + (activity * 1) + (nursing * 1);
	
	doc1.dresult.value = Math.round(dpoints);

}

// -->

Hello everyone,
I've been scratching my head over this one for quite a while.

I'm having trouble running two different scripts on my site- one named accordion and the other named lightbox. I think that it might because of a similar behavior in both the scripts (and if I had to guess I'd say maybe its preload.)

I'd appreciate any help/questions. The page that I'm having the problem with is he http://lehdesigns.com/bearpaws.html

And here are the codes..

Lightbox
Code:

LightboxOptions = Object.extend({
    fileLoadingImage:        'images/loading.gif',     
    fileBottomNavCloseImage: 'images/closelabel.gif',

    overlayOpacity: 0.8,   // controls transparency of shadow overlay

    animate: true,         // toggles resizing animations
    resizeSpeed: 7,        // controls the speed of the image resizing animations (1=slowest and 10=fastest)

    borderSize: 10,         //if you adjust the padding in the CSS, you will need to update this variable

	// When grouping images this is used to write: Image # of #.
	// Change it for non-english localization
	labelImage: "Image",
	labelOf: "of"
}, window.LightboxOptions || {});

// -----------------------------------------------------------------------------------

var Lightbox = Class.create();

Lightbox.prototype = {
    imageArray: [],
    activeImage: undefined,
    
    // initialize()
    // Constructor runs on completion of the DOM loading. Calls updateImageList and then
    // the function inserts html at the bottom of the page which is used to display the shadow 
    // overlay and the image container.
    //
    initialize: function() {    
        
        this.updateImageList();
        
        this.keyboardAction = this.keyboardAction.bindAsEventListener(this);

        if (LightboxOptions.resizeSpeed > 10) LightboxOptions.resizeSpeed = 10;
        if (LightboxOptions.resizeSpeed < 1)  LightboxOptions.resizeSpeed = 1;

	    this.resizeDuration = LightboxOptions.animate ? ((11 - LightboxOptions.resizeSpeed) * 0.15) : 0;
	    this.overlayDuration = LightboxOptions.animate ? 0.2 : 0;  // shadow fade in/out duration

        // When Lightbox starts it will resize itself from 250 by 250 to the current image dimension.
        // If animations are turned off, it will be hidden as to prevent a flicker of a
        // white 250 by 250 box.
        var size = (LightboxOptions.animate ? 250 : 1) + 'px';
        

        // Code inserts html at the bottom of the page that looks similar to this:
        //
        //  <div id="overlay"></div>
        //  <div id="lightbox">
        //      <div id="outerImageContainer">

Hi, First, let me preface by saying that I know very little about JavaScript. I have found and modified a nice image gallery script to my liking, but now I'm trying to put this script multiple times on the same page. I read the Frequently Ask Questions section (http://www.codingforums.com/showthre...913#post178913) and have learned that my two options are to rename all of the variable and function names so they're unique. I've tried this, and I don't think I've completely renamed them all in the correct locations. I also see that you can make them Object Oriented. I've read the several threads on this, and I think it's a bit over my head. I was hoping someone would be able to review my code below and provide some suggestions/insight as to what I need to change. Your help is greatly appreciated.

Thanks,

Ben.

Code:

Could someone please change this line so that it respects the global namespace:

Code:

var selected = students.options[students.selectedIndex].value;

The error console is telling me to use document.getElementById but I don't know where to put it.

Thanks.

I'm a total noob who decided to learn som web programming, I hope it's okey to post such questions here.

I've written a script to learn how to fill in a value into a textarea by a button click. (See below.) I get it to show the selected number of each button, however the numbers just flashes and disappers right away. I want it to stay in the textarea. How do I do that and why does this problem appear?

Head section
<script type="text/javascript">

function calculon(i)
{
document.forms['siffror'].elements['test'].value = i;
return;
}
