Steven,

I'm afraid I don't understand, what you proposed. What is ekp? Why it should be Public? I don't think Public is a good idea at all, and you can see several Jim B. postings about using 'Public'.

I was thinking about valid/LostFocus method, in which I should go through all lines in editbox and check len(alltrim(mline(...))=5 and isnumeric(). But may be this approach is not sufficient.
