This might be hard to explain...

I want to check a sheet for a persons name AND if an X is entered in an
associated cell. In literal terms the IF statement would be as follows:

IF ("John Doe" is found in range A1:A99 AND there is an X in field B1, THEN

The X would appear in the same row as the name in the range, for example:
Field A1 contains "John Doe" and field B1 contains "X".

How would I make this work?
