I am trying to get total to calc on a form.
I have three fields that I want to add together and display in the Total field.

Sub-Total:
Shipping:
Sales Tax:

Total:

On the first three fields I use onChange="CalcTotal()"

For this function I am using:
 SubAmt = document.form1.SubTotal.value;
 ShipAmt = document.form1.Ship.value;
 TaxAmt = document.form1.Tax.value;
 GrandTotal = SubAmt + ShipAmt + TaxAmt;
 document.form1.TotalPrice.value = GrandTotal;

If I enter 1 in each of the three fields my total is 111. How do I make it return 3?

Thanks,
David

Try this:

GrandTotal = parseInt(SubAmt) + parseInt(ShipAmt) + parseInt(TaxAmt);

How do I maintain the decimal point? ie 1.25 + 1.25 + 1.25 = 3.75 not 4?

thanks,
David

Try parseFloat or search for Math.round.

ParseFloat worked!

thanks for the help
