Loop to do sum value....

[NinjaTurtle]

function updatetotal(num) {
var sum=0
var y=document.form1.totalrecord.value // i will get 10.
var sum=
for(var d=0;d<y;y++){
parseFloat(document.form1.amt1.value)+parseFloat(document.form1.amt2.value)+parseFloat(document.form 1.amt3.value)+parseFloat(document.form1.amt4.value)+parseFloat(document.form1.amt5.value)+parseFloat (document.form1.amt6.value)+ ... parseFloat(document.form1.amt10.value)
}

sum = roundoff(Math.round(sum*Math.pow(10,2))/Math.pow(10,2));
document.form1.total.value=sum
}


Instead of write "parseFloat(document.form1.amt1.value)+...parseFloat(document.form1.amt10.value)"

can i do it in a loop???how? use elements?

Sure, use something like:

var total=0

for(cfield=0;cfield<totalfields;cfield++)
{
total+=parseFloat(document.form1['amt'+cfield].value)
}
