Cancel error
 

First,can someone tell me where to read what this is/does?
VBHelp says nothing.

Second queston I'm returning a value (integer) from a
input box and getting error 'type mismatch' when clicking
Cancel (or escape).
I read here how to check against the "" that Cancel
returns but I can't because of teh mismatch.
I'd also like to validate the input (no text, two digits,
no decimal point) data but don't know how .
THanks in advance for any help you can give to all these
questions.
