Internet Explorer Not Rendering Onchange In A Dynamic Form

I have created some Javascript to make a form application dynamic. My problem is that the code works in every browser except for internet explorer. I get no errors from Firebug and I have made sure that internet explorer has javascript enabled. I am completely in the dark as to why this would be happening. It works perfectly in Firefox, Chrome, and Safari. Here is my entire code for the form, it is for a housing application for a college,

Code:
function runAll2 (processPart, areaType, spaceType, mealType) {
pp = document.getElementById('fld2416');
at = document.getElementById('fld2417');
st = document.getElementById('fld2418');
mt = document.getElementById('fld2481');

[code]....

This for is supposed to go live on Tuesday and I didnt realize that it wasnt working in IE until today. I am pretty good at HTML and CSS and know a bit about cross browser testing, I just didnt even think about it because this form is entirely ASP and Java, my bad.
