I am using =AVERAGE(Start:End!F37)
some of the sheets contain a zero in cell B37

Which cell is it, B37 or F37?

A single formula to do this can be really complicated (especially if you
need an error trap).

You would be better off using a formula on each individual sheet that checks
for 0.

On each sheet in say, cell X1:

=IF(F37=0,"",F37)

Then you can still use the much simpler:

=AVERAGE(Start:End!X1)

I am using =AVERAGE(Start:End!F37) to calculate an average across multiple
worksheets. However, some of the sheets contain a zero in cell B37. I
need
to ignore that zero (and that sheet) entirely. Can anyone help?
