I have 3 columns, one with date i.e. 19/11/2012, on with time i.e. 17:53:00 and then I will have a 3rd which I want to autofill depending on what is in columns 1 and 2.
I want the end result to be: 20121119175300, so the date changed around and added to create a unique number.
Can this be done or not?
