I'm trying to allow multiple entries for a person into a table and restrict one entry per date. So, there could be multiple entries for person X, but only one per day. I have found numerous ways to validate data with conditional formatting and VBA and I'm not opposed to use either; however, have not found a specific example to my problem. Anyone have any ideas?

Whats the difference between CONCAT and CONCATENATE?
The newer CONCAT function can reference a range of cells. =CONCATENATE(A1,A2,A3,A4,A5) becomes =CONCAT(A1:A5)
