Which fields on the form denote the quantity and which denote the cost? You are wanting the "total price" to contain the calculated value of the (price per unit * quantity of that unit), is that correct?

To display a dollars & cents value from mulitplying qty x amount, I use the following:

*/ adds zeroes if exact change
function cent(amount) {
return (amount == Math.floor(amount)) ? amount + '.00' : ((amount*10 == Math.floor(amount*10)) ? amount + '0' : amount); }

function amtTotal() {
document.form.subttl.value = cent(Math.round(((document.form.qty.value - 0) * (document.form.sellprice.value - 0))*Math.pow(10,2))/Math.pow(10,2));}

There's always a better way. The fun is trying to find it!
