Hi
Its been commonly asked on here but the formulas I have tried don't seem to work.
I need a countif function to count values in column C (excluding duplicates) but only if cells in column I are blank.
Thanks
Don

Post some sample data and tell us what results you expect.

As requested
Try this array formula**:
=SUM(IF(FREQUENCY(IF(I6:I12="",MATCH(C6:C12,C6:C12,0)),ROW(C6:C12)-ROW(C6)+1),1))
** array formulas need to be entered using the key
combination of CTRL,SHIFT,ENTER (not just ENTER).
Hold down both the CTRL key and the SHIFT key
then hit ENTER.
It says N/A
I have {=SUM(IF(FREQUENCY(IF(I6:I900="",MATCH(C6:C900,C6:C900,0)),ROW(C6:C900)-ROW(C6)+1),1))}
If there are empty cells in the column C range you'll get that error.
To account for empty cells try this version:
=SUM(IF(FREQUENCY(IF(I6:I900="",IF(C6:C900<>"",MATCH(C6:C900,C6:C900,0))),ROW(C6:C900)-ROW(C6)+1),1))
Still array entered.
That's great.
Thanks for that.
You're welcome. Thanks for the feedback!
No problem
