Verifying data entry

Hi, I am trying to figure out a way to verify a piece of data entry.
Study ID is in the form of two letters and three numbers (I'm using
the input mask LL000. The first letter will be 'm' for male or 'f'
for female, and the second letter will be 'c' for case and 'x' for
control. There is a separate field for case or control, and boss wants
to make sure that the code matches the case/control field. Can anyone
help me code a macro to check this? Thanks!

Take a look at the BeforeUpdate event for the record. That would be a good
place to do this kind of validation checking.

Laura -

In the BeforeUpdate event, place code like this:

If Mid(Me.[Study ID],2,1) Me.CaseControlField Then
msgbox("Study ID does not have the correct case/control value")
Cancel = True
End If

The field names will need to be what you have on the form. You can put
whatever in the msgbox you want the user to see. The Cancel will cause the
record not to be written.

Thanks for the help! I tried putting the following in the validation
rule: =([ID001]='*c***' And [FB008]=1) Or ([ID001]='*x***' And [FB008]
=2) but it's popping up the validation text every time. Could this
approach work? Thanks again!
