Hi,Make sure the Qty fields in all of the rows are NumericFields. I
suspect that they are TextFields, which means that the data in them will
be treated as a string and not a number. Hence the result you are
getting. You can force the script to make the inputs numeric, but it
would be much better and easier if the Qty fields were numeric. By the
way, within a form you can have a mixture of JavaScript and FormCalc.
The only real restriction is that you can't mix the two within the one
event. Niall
