Using Excel 2003's Data Validation feature (rather than VBA code), is it
possible to create an input mask? Specifically, I need to test for certain
valid characters in a Project ID as follows:

Example: PA264.04

Position 1: can be either a "B" or "P"
Positions 2-5: can be either uppercase letters or numbers
Position 6: must be a decimal point
Positions 7-8: can only be numeric (00 - 99)

Any help would be greatly appreciated. Thanks.
