Errrr...i don't think i understand your answer...
where should i put that code?
Maybe i should use the real program as an example :

command2 adds

4
6
8
3
2
3
5

to the textboxes i mentioned before (A to G)
Assuming we use your code, when i click command2,
it has to go through your code like this :

"add 4 to textbox A", textbox A runs your code because there's an item in it.
"add 6 to textbox B", textbox B runs your code because there's an item in it.
and so on until textbox G

So what code should i put in command2 to prevent your code from running?
