Hi All.. I am angry cause its such a little thing but its a big part of my project so Here is the scenario.. I have an access database with a table called People and a Field called Names.. In the Names field I have five entries.
A
B
C
D
E

I want to be able to have an excel macro that If Range("A1") = (Something in the Field Names) Then Range("B1") = This Person Is There.. For example: I would type in "C" at Cell A1 and I would click this button and it would say "This person is there" in cell B1.. Thanks for the responses..
