I need to put an input mask on my form for serial numbers of cell phones.
They can be either 8, 11 or 15 digits in length ONLY. If 8 digits, they can
be alpha-numeric (0-9 & A-F ONLY - Hexidecimal). If 11 or 15, they must be
ALL NUMERIC. It is very important to us that the serial numbers are entered
correctly and that the system stops the user as much as possible from
entering an incorrect one. I realize this may require a small amount code on
that field, but either way, I need assistance on how to do this. The current
input mask on that field is >AAAAAAAAaaaaaaa

Thank you, as I really would appreciate any help you can offer on this
