JS Validation, Math Problem in JS Validation Options

[Ollie]

Does anyone know of a work around for the following problem?

http://mdwvo.com/oysters/contactform.php
Validation Output: 1 Error
Line 120, Column 43: character "<" is the first character of a delimiter but occurred as data
while(num.length - num.indexOf(".") - 1 < ✉
This message may appear in several cases:

You tried to include the "<" character in your page: you should escape it as "&lt;"
You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&amp;", which is always safe.
Another possibility is that you forgot to close quotes in a previous tag.

Line 120, Column 43: StartTag: invalid element name
while(num.length - num.indexOf(".") - 1 <

Here is the entire JS:

<script language="javascript" type="text/javascript">
var RATE=.06;/* percent rate for shipping */
function addTotals() {
with (document.forms["f1"])
{
var totalResult = Number( size.value ) * Number( qty.value );
var _total = roundTo(totalResult,2);
sub_total.value = _total;
var _tax = roundTo((totalResult * RATE),2);
tax.value = _tax;
total.value = roundTo(parseFloat(_total) + parseFloat(_tax),2);
}
}


function roundTo(num,pow){
if( isNaN( num ) )
{
num = 0;
}

num *= Math.pow(10,pow);
num = (Math.round(num)/Math.pow(10,pow))+ "" ;
if(num.indexOf(".") == -1)
num += "." ;
while(num.length - num.indexOf(".") - 1 <
pow)
num += "0" ;

return num;
}

</script>

The problem is that "&lt;" does NOT function as a Math Operator.

Use an external script file (the better choice) or use the CDATA hack.
