depending on where you are trying to use this, you might also want to try:
=DCOUNT("SomeField", "tablename", "[job] = 'football_Player'")
If you are doing this in a query, or in a control in the header or footer of
a continuous form, I think Bob's answer is what you are looking for. If you
are doing this in a query, or in an unbound text box on a form, I think you
will want to use the DCOUNT( ) function.
