    Try with this code in javascript..

    function recipt()
{
var a = Number(document.f1.amount.value);
var b = Number(document.f1.quantity.value);
var pro = a*b;
var per=0;
if (pro > 100)
{
    var c = Number(document.f1.discount.value);
    per = Number(pro * c / 100);
    var d = Number(document.f1.subtract.value);
    document.f1.subtract.value = per;
    }
var e = Number(document.f1.total.value);
var total = pro - per;
document.f1.total.value = total;
}
