How to get value from span element in Firefox?

Hi all,

The script below works as expected in IE6 and IE7.  When I try it in FF3, it returns a NaN where IE returns an actual value.  For testing purposes, this script just doubles the selected value in the list and outputs it to a span element.

I've even included an isNaN() test, but it's still not working.

Can anyone make this work in both IE and FF?

Any help much appreciated.

Thank you,

Paul.
<html>
<head>
<script>
function updateprice(labelParam, selectParam, spanParam) { // output area, number selected, item value
// query DOM set for specific elements by ID
var label = document.getElementById(labelParam);
var name = document.getElementById(selectParam).value;
var spanval = parseInt(document.getElementById(spanParam).value);
if (isNaN(name)) { 
	name = "0"; 
	name = parseInt(name); 
	alert("name problem. val: " + name);
}
if (isNaN(spanval)) { 
	spanVal = "0"; 
	spanVal = parseInt(spanVal); 
	alert("spanval problem. val: " + spanVal);
}
var total = parseInt(name)*parseInt(spanval);
msg = "Result: " + total;
label.innerHTML= msg;
}
 
 
</script>
