Form stops working

[jcalar]

I am using an online form with calculation done in Javascript that someone else started. I have used it on two different sites for a shopping cart type effect, but with the second site I am only able to add a certain number of items and then the form will not submit in IE for PC. Up until a certain number I haven't yet determined, it works fine, but I hit a point where you click Submit and it does nothing. Works just fine on a Mac though! If it helps, a working version of this script is on

http://www.americanbrittanyrescue.org/help/order_cc.html.

Here is a condensed version; note I first have a script for a popup window, but that does not seem to interfere.

<script language=Javascript>

function openphoto(html) {

open_window =
window.open(html,&quot;photo&quot;,'toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=no,resizable=0,width=400,height=400');
if ((browser==&quot;Microsoft Internet Explorer&quot; && ver<=3) || (ver<3)) {
} else {
open_window.focus();
}
}


var NumItems;

function roundOff(value) {
value = &quot;&quot; + value //convert value to string
precision = 2;

var whole = &quot;&quot; + Math.round(value * Math.pow(10, precision));

var decPoint = whole.length - precision;

if(decPoint != 0) {
result = whole.substring(0, decPoint);
result += &quot;.&quot;;
result += whole.substring(decPoint, whole.length);
} else {
result = whole;
}

if (result.length < 7) {

if (s1 < 1 || s1 > 99) return 0;
if (s == &quot;&quot return 0;
NumItems = NumItems + parseInt(s1);
return (s1);
}
