Re: Automatically adding the date/time to a cell when another cell is updated

Hello Haytham, I know this thread is quite old. And I got this code to work perfectly in my MacBook excel. However, when I increase the Range from ("B2:B10000, through, BK2:BK10000") then for some reason it stops working. Even when reducing it back down to only be 99 lines per column it breaks. Any idea why?
