Okay, in this case, you would use the following formula...

=IF(INDEX(FREQUENCY((F1:F3,F5),0),2),AVERAGE(IF((1-ISNUMBER(MATCH(ROW(F1:
F5),{4},0)))*(F1:F50),F1:F5)),"")

....confirmed with CONTROL+SHIFT+ENTER. Note that the number in the
array constant --- {4} --- determines which row to exclude, in this case
row 4 or F4.

If, for example, you wanted to exclude rows 2 and 4 (F2 and F4,
respectively), then you would change the array constant to {2,4}. Does
this help?

Ok! Took care of that problem but it is not excluding f39,f40,f41,f46,f47.
I see where the values of {5,6,7,12,13} should take care of this. Maybe we
got off course somewhere. Here is a simple version of what I want to do

f
1 10
2 12
3 0
4 0
5 7

OK, I want the average of f1,f2,f3,and f5 but do not include the zero value
located in f3 in the average calculation. Also, do not include f4 in the
calc. This is overly simplified but if you get this to work, I could get the
remainder.

Thanks again.
