Hi folks, I'm new to the message board and had a question (of course). I'm looking to use Excel to validate an inventory. I have two columns of data, 'Asset Tags' and 'Serial'. I want to have Excel conditionally format a cell in a third column 'Validate' if it appears in 'Assets' or 'Serial' based upon a checkbox status. i.e., if the checkbox is TRUE, the Excel compares the items in 'Validate' column, to 'Assets', if the box status is FALSE, it compares the 'Validate' value to the 'Assets' column. I was looking to do this without VB if possible. Thanks!
