My situation is similar but I haven't been able to customize this to work
like I thought I should be able to.
I have one cell in multiple tabs I that want to include in the average, as
long as they <0. If anyone of them <0, then I do not want that particular
cell to be factored into the result because it skews the average (because
it's a month that hasn't occured yet so the data is 0). Here's my
(nonworking) formula if anyone can help:

=average(if(jundata!b2,juldata!b2,augdata!b2,sepda ta!b2,octdata!b2,novdata!b2,decdatab2<""),jundata !b2,juldata!b2,augdata!b2,sepdata!b2,octdata!b2,no vdata!b2,decdata!b2)

One way (array-entered: CTRL-SHIFT-ENTER or CMD-RETURN):

=AVERAGE(IF((A3:A45="Photo")*(H3:H45<""),H3:H45))

This is the array I'm using to try to determine an average. Problem...if
the field is blank it's counting it as zero and lowering the results. It
figured 79% when it should have been 94%. 94% was returned using the simple
average formula. I'm guessing I need to nest something to not count nulls?
Help!!!
