It didn't work. It didn't put the {} around it. I did what you said to do.

Hi,

Try this ARRAY formula

=AVERAGE(IF(B1:B20="X",C1:C20))

This is an array formula which must be entered by pressing CTRL+Shift+Enter
'and not just Enter. If you do it correctly then Excel will put curly brackets
'around the formula {}. You can't type these yourself. If you edit the formula
'you must enter it again with CTRL+Shift+Enter.
