I am sure this is pretty basic for most of you, but I am truly a novice in Excel formulas so here goes. I would like to display the results of the average of 2 different cells but only if the average of the two cells is less than a specified amount. The problem I am having is that if the average of the 2 cells is greater than the specified amount, the formula cell automatically displays the value of cell #1, when I wish it would display 0 (zero). So for example:

=AVERAGEIF(B9:D9,"<20")

Is there an additional argument that I can add to have the formula display a zero in the event that the average of B9 and D9 is greater than 20?

Thank you all!
