Condition based on multiple cells

[WAR]

I would like to look at 3 cells: A6, C6, E6. If all 3 of these cells are
blank, I would like to return a blank cell. If any of the 3 cells has a
value, I would like to return the average.

I am familar with how to do this based on 1 cell, but confused as to how to
get it to work with 3!

=IF(AND(A6="",C6="",E6=""),"",AVERAGE(A6,C6,E6))

 

[Bob Umlas]

=IF(COUNTA(A6,C6,E6)=0,"",AVERAGE(A6,C6,E6))
