In google sheets, I would like to apply conditional formatting to any cell in Col A that matches the value of any cell in the range B3:B11 See sample image.
I tried "custom formula is": =A3=B3:B11 over the range A3:A11, but that created unexpected results
If you have both text or numbers you can use this:
=SUM(--ARRAYFORMULA(OR(A1=$B$3:$B$11)*(A1<>"")))
