Can anyone point me in the right direction. I have 2 simple calculators on my web page that i want to compute different values. At the moment they return the same value even though base number is different. I would also like to have the option to imput area as a value as well as calculated. I am very new to web design and apologise in advance if this is an elementry problem. Code I have written as follows:

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function compute(form) {
var areacalc = (form.length.value * form.width.value) *1;
var costcalc = areacalc * 10;
areacalc = twoDecs(areacalc);
costcalc = twoDecs(costcalc);
form.area.value = areacalc;
form.cost.value = costcalc;
}
function twoDecs(item) {
return eval(parseInt(item * 100) * .01);
}
// End -->
</script>
