Finding Duplicates across Multiple Tabs

[mmac723]

I'm trying to label rows as "Duplicate" in Column Q if i have a duplicate phone number in Column G across multiple tabs. I'm struggling with the formula.
So far, I have:
=IF(COUNTIFS($G$8:$G$2020, G8, 'FW 4'!$G$8:$G$2020, G8),>1,"Duplicated","")

But it's not recognizing the second Criteria Range from another tab.
What am I doing wrong?

Thanks y'all!

=IF( COUNTIFS($G$8:$G$2020,G8,'FW 4'!$G$8:$G$2020,'FW 4'!G8)>1,"Duplicated","")

plus remove the comma after the last parentesis.

If you are trying to evaluate G8 of the first sheet against both sheets, then in the second part of the CountIfs, use the first Sheet name with the G8:

=IF( COUNTIFS($G$8:$G$2020,G8,'FW 4'!$G$8:$G$2020,Sheet1!G8)>1,"Duplicated","")

But with no sheet specified, Excel gets confused about which G8 you really want to evaluate.

Thank you for your response!
I've tried it, and it doesn't seem to be working. The 'FW 4'! Range is what's not being recognized.... So it's not reading that G8 in FW 5 is a duplicate on that sheet now. (Does that make sense?)

Read Post #3 also. it gives further explanation about using a sheet name with the second G8 reference. Note in my example that it is completely different than that in your post #4. If you post the sheet name for your active sheet, I will write the correct formula for you to copy and paste into the cell.

I tried both, and neither gave me the correct answer, or an error code for that matter. The cell is just blank (And I have duplicates in the field to test the formula.)

Is there a better formula to work, like MATCH?

They worked for me, so I don't know what else to offer at this point.

If you post the sheet name for your active sheet,

What is the response to the above? That is, the sheet name that the formula is in.

If you want to know if the phone number appears on the same row in each sheet (that is 'FW 4' and the sheet the formula is on) then all you should need is
=IF(AND('FW 4'!G8=G8,G8<>""),"Duplicated","")

If you want to know if the same phone number appears anywhere in column G of both sheets (that is 'FW 4' and the sheet the formula is on) then
=IF(COUNTIF('FW 4'!$G$8:$G$2020,G8),"Duplicated","")
