Average non-adjacent cells & exclude zeros

[Danni2004]

I want to find an average of three cells that are non-adjacent and will
occasionally have a zero in it.
Example:
=AVERAGE(H12,V12,AJ12)

How can I rewrite this so that the formula will not include the cell in the
average if its value is zero?

Thanks!

One way

=AVERAGE(IF((MOD(COLUMN(H12:AJ12),14)=8)*(H12:AJ12<>0),H12:AJ12))


needs to be entered with ctrl + shift & enter

this assumes you have the same number of columns between each value like you
have in your example

Thanks Peo.
Can you clarify what the "8" is for in this formula?
Also, I've seen other posts with the Ctrl + Shift & Enter before. Can you
explain why you have to use this?

What are the column numbers for H12, V12, and AJ12? What does
MOD(column_number,14) return in each of those cases?

Control Shift Enter is used to enter an array formula. look up array
formula in Excel help.
