Hi. As per the title, I am using the following formula:
=IF(AND($U$15=3,COUNTIF($B$21:INDIRECT(Sheet2!D17),B21)>3),TRUE,FALSE)
where Sheet2!D17 cell value = B33. Excel will not let me do this saying that I may not use reference operators. Is there another way around this? FYI the range in the CF formula needs to be dependant on the number of cells that have values in them.
