Like this? I took out the hyphens, but for scanability, I formatted the 'count' with leading 0's
Although, it's not clear to me why you need it since just the row number would be a unique indentifier
That worked perfectly. Thank you! I need a unique identifier bc I intend to reference it in a difference section of the project. For use in a vlookup or index match specifically. Does that make sense or am I going about it all wrong?
