Calculating Average of Certain Cells
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.
