I have an excel workbook with multiple worksheets.
I want to be able to detect if any duplicate data has been inputed into all of the worksheets.
If this is detected, I want it to highlight the duplicate cell.
Is there a way to have this check the data after every entry?
I was fooling around with conditional formating and the countif function, but it is highlighting the wrong cells and I can not get it to detect data from other worksheets.
any help would be appreciated.
