Javascript Math & IE

Hello,
I have made a basic javascrpt math function to add up some checkboxes
Unfortunately it does not seem to work in IE (PC). I have used it successfully on Firefox (Mac) and Safari (mac), but it is a no go on IE. It is the section of the following page ([url]http://fuzefit.com/enroll/signup.html[/url]) where TUITION prices are added 2/3 the way down. The basic formula result (total) works but if you click “add elective classes” which does a little extra math, it does not compute using IE (total2, total3, total4).

Any thoughts? Make Sense?

The little script that figures the extra math

<script language=”javascript”>
function doCalculate()
{
//with document.ENROLL.myForm –> oops!
with(document.ENROLL)
{
total2.value = Math.round(total.value – 149);
total3.value = Math.round(total2.value * 1.1);
total4.value = Math.round(total3.value * 1 + 149);
}
}
</script>
