Hi All

I have a workbook, with multiple sheets, in one of those sheets however I wish to make Cells in Column A & B mandatory assuming data has been entered into a new row in any of the other corresponding cells ( C through P)

It would also then be useful if a message (as a reminder) was presented to inform users that data must be added to Columns A & B.

I am relatively new to VBA/ Macros, having done some basic routines, I have looked at this one for hours/ days and have been unable to progresss so far.

Thank you all in anticipation of your help

Mark
