@Jenner_uk: To ask a good question, you should provide information in a form that is clear and precise, so that others could understand. E.g., “I have “this” in A1, “that” in A2; and I use “XYZ” conditional formatting with “some” formula; and I get this unintended result, instead of this intended”. Or better “Here is my sample file with sample data and here is clear description of the problem as above”…
