Write your reply.

assistant: Hi Andrea,
 I think your trouble is in Form_Unload. There you set everything in your
 tartmp array to zero.
 I have a few comments/suggestions below too. I don't know any Italian so
 I could only figure out a few words in your comment lines.
 Why not make the variables Integer?
 You could use Select Case here with these Options.
 What does the Mostra routine accomplish? It seems to take text, turn it
 into values, and then turn it back into text (strings) again. Right back
 where you started. Oh, wait a minute... op = x changes op, doesn't it?
 Also, you probably should use IsNumeric to see if these text strings can
 be turned into numeric values unless you are limiting user input in the
 KeyPress event.
 Same suggestion here about IsNumeric.
 And here about Select Case.
 If it's not Visible, you really don't need to worry about setting Enabled
 to False.
 'Call' is optional; I rarely see it used in VB. Saves typing 4 letters, one
 space, and 2 parentheses.
 Ah, here's the Select!
     tartmp(dd, ta, oo) = 0  'Whole array gets zeroed out here.
 Again, I think this last routine is the culprit.
 HTH,
 Gary
... ARRRRRGGGHHH!!!! ... Tension breaker, had to be done.
