Hi,
Why is the total line in first picture empty..?
Hmm, I got the form running, but sorry, I can't reproduce the problem, no matter what I try:
Another advice, if you want to spare yourself long hours looking for the cause of "weird" problems: do not use character fields for calculations, even if it seems to work. Don't take shortcuts there - use proper numeric formats for calculations.
cheers
