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)

'OR having the sheet names in J1:J3 (no blank cells)
=SUMPRODUCT(SUMIF(INDIRECT("'"& J1:J3 &"'!F37"),"<>0"))/
SUMPRODUCT(COUNTIF(INDIRECT("'"& J1:J3 &"'!F37"),"<>0"))
