I use the AVERAGEIFS function for getting a numeric value based on multiple criteria. If you are not confident that the criteria would only return one value, then you can wrap in a COUNTIFS statement.

=IF(COUNTIFS($A$1:$A$10, crit1, $B$1:$B$10, crit2) = 1, AVERAGEIFS($C$1:C$10, $A$1:$A$10, crit1, $B$1:$B$10, crit2), #N/A)

This only works for numeric values though.
