PHP - Total Beginner Plea For Help - Formmail.php

Hello all, thanks for everything you do!

I used a php from generator to make the form seen on this page:
http://www.firstpresgreenville.org/forms/retirementform/retirementform-alt.html

I need to be able to click on the check boxes and get a dollar amount total in the total field....So if you checked "single", the total field would read $40, and if you checked on "couple", the field would read $50...simple as that...

Is there anyway to make that happen? 

This is the code I am working with now....

<?php

# This block must be placed at the very top of page.
# --------------------------------------------------
require_once( dirname(__FILE__).'/form.lib.php' );
phpfmg_display_form();
# --------------------------------------------------



function phpfmg_form( $sErr = false ){
        $style=" class='form_text' ";

?>

Hello I am very new to php and programming and I need a grand  total of "$Total = odbc_result($result, "total");" but not sure of how to create it.

    <head>
        <title>Sum Html Textbox Values using jQuery/JavaScript</title>

$(function() {
    $(document).on('blur keyup', '.add, .sub', function(e) {
        var sum = 0;
        $('.add, .sub').each(function(i) {
            if (!isNaN(this.value) && this.value.length != 0) {
                if ($(this).hasClass('add')) {
                    sum += parseFloat(this.value);
                }
                else {
                    sum -= parseFloat(this.value);
                }

I apologize if this isn't the exact right location for this question, but it's the best place I could find.  I work for a small business and the server hosting our website recently disabled FormMail.  We no longer have a webdesigner per se and I've been the one taking care of the website.  Unfortunately the few programming classes I've taken have mostly left me by now and I'm banging my head against the wall trying to find a way to get back our multiple feedback forms.  I'm sure the best thing would be to hire someone, but business hasn't been great and the boss is counting on me, so I'm hoping someone here may have some suggestions.  I've been corresponding with our server trying to get some suggestions on what to do and this is the best they've been able to tell me;

"The reason being that Shared Servers must have
the ability for php/cgi to send mail disabled as a protection against
darkmailer, so any form or scripts that would send mail must be able to
authenticate itself to the server as a valid user."

"If you can find a method to send the
mail without php/cgi, or one that does go through the steps to authenticate as
a valid user (specifically, as you), then we can probably get you all set up."

"The only option at this point would
be to correct your script to authenticate as a valid email user."

"...you would need to change your scripts to
login with a mail user to authenticate and send mail."

Now I'm not completely programming illiterate; I mean, I passed my classes in college, but I can't figure out how to do this.  They say they don't allow any FormMail or FormMail Clones, so I'm fairly lost.  If anyone has any helpful hints or suggestions I would appreciate it greatly.

Thanks,
Zach

Hi

I need assistance in finding the code to produce a total of all the subtotals in my shopping cart.  Not sure how to assign an attribute to the table cell because a new row is generated each time a customer adds to cart.

Attached is a pdf of a screenshot and script for the cart.

Thanks
