I perform a lookup where the results could populate one cell or as many as 15

How do I get it to ignore the #N/A when performing the average?

Use this **array** formula:

=AVERAGE(IF(NOT(ISNA(rng)),rng))

To enter an **array** formula, hold down <ctrl<shift while hitting <enter.
Excel will place braces {...} around the formula.
