So i have cell range on another sheet, say D5 to F25 with data. Simple list on Serial Number (SN1001, SN1002, etc). Is there a way to reference these values from another sheet with conditional formatting to turn a cell yellow is there's a match? Like if Sheet 1 Cell D5 says "SN1001" and Sheet 2 has "SN1001" in the listed range it turns yellow. I know i can do it cell to cell, but i need to reference about 75 SN's and i keep getting a reference error. Any help would be great, thanks.
