One way:
=IF(PRODUCT(Z6:AE6)=0,0,AVERAGE(Z6:AE6))

Won't that return zero if there is a zero anywhere in Z6:AE6?

Perhaps:

=IF(SUM(Z6:AE6)=0,0,AVERAGE(Z6:AE6))

or

=IF(SUM(Z6:AE6),AVERAGE(Z6:AE6),0)

I have a spreadsheet where, cell U6 is an average of Z6-AE6. i also
need U6 to =0 if any cell within Z6 - AE6 is a 0. ...

One way:
=IF(PRODUCT(Z6:AE6)=0,0,AVERAGE(Z6:AE6))

Caution: an empty cell doesn't count as zero with this formula. Neither
does text.
