Hi

Try this:

=If(COUNTIF(C14:C52,C14:C52)=0,0,SUM(1/COUNTIF(C14:C52,C14:C52))-10)

Thanks Jacob, but that didn't work, I know that the formula I gave below worked before, because it is still working in the sheet, but I need to change the cells it is counting...

I know there was somthing you had to do with it to stop the div/0 error, I just can't remember what it was.

Thanks

Hi

To stop the Dix/0 you check to see if what is in the demoninator is 0 first if it is then display whatever value you want if not then do your calculation. You could also use conditional formatting to make the div/0 white text so it would be invisible.
