simple script working with IE, but not with firefox

[photoxprt1868]

Hello,

Does anybody have an idea why this script is not working in fireFox. It works perfectly in IE

Here's the script

<SCRIPT LANGUAGE="JavaScript">

function calculateCost(kwh){
var custCharge2005 = 5.25;

var first750kwh = 0.04302;
var first750 = 0;
var over750kwh = 0.05232;
var over750 = 0;
var fuelCharge = 0.04009;

var custCharge2006 = 5.17;
var first1000kwh = 0.04231;
var first1000 = 0;
var over1000kwh = 0.05231;
var over1000 = 0;
var fuel1st1000kwh = 0.0584;
var fuelOver1000kwh = 0.06841;


if (kwh > 750){
	first750 = 750;
	}
	else{
		first750 = kwh;
	}

if (first750 < kwh){
	over750 = kwh - first750;
	}
	else{
		over750 = 0;
	}

var cost2005 = custCharge2005 + (first750kwh * first750) + (over750kwh * over750) + (fuelCharge * kwh) - 1.36;
<!--1.36 is the gross reciept tax -->

if (kwh > 1000){
	first1000 = 1000;
	}
	else{
		first1000 = kwh;
	}

over1000 = kwh - first1000;

var cost2006 = custCharge2006 + (first1000kwh * first1000) + (over1000kwh * over1000) + (fuel1st1000kwh * first1000) + (fuelOver1000kwh * over1000);

//alert(cost2005);
//alert(cost2006);
compareForm.charge2005.value = cost2005;
compareForm.charge2006.value = cost2006;
}
</script>

and this is how I call it

<img onClick="calculateCost(compareForm.kwh.value);" src="images/blubvtop.gif" width="68" height="20">

Thank you

Try using document.compareForm.... when you access the form elements.
