Hi

I want to limit the content of a cell based on what is entered in another
cell. For example if I enter "John" in cell A1 then in A2 I only want to be
able to choose from "Smith" or "Jones". But if I enter "Mary" into cell A1
then in cell A2 I only want to be able to choose "Jackson", "Bush" or
"McKenzie".

Is there a way I can do this in Excel 2002 (XP) using a macro or some sort
of VBA code?

Hope someone out there can help. Thanks in advance.
