What?

Can you show some code? or is currency manager another software?

Not clear please elaborate.

Welcome to the forums,

I Think I understood what you want.

Basically you want the user to select something from the first combobox, depending on the response you want to fill the second one, and depending on the second you want to fill the third one.

Right?

If so your code looks good, some syntax errors, but logic seems fine could you please elaborate a little bit. Your code is a little hard to read without code tagging, I have flagged your post so a mod will do that any time now.
