Looking for formula that will confirm (True/False) that the (single
character) entry in col "C" is a valid entry for data in col "A". I have
setup a table that shows the 9 codes in col "A" (a, b, c, d, e, f, g, p,
and
q) and the codes that correspond to them.

Any assistance appreciated

Thanks in advance.
