Hi
Three simple macros will do this for you.
The first one will run when you open the workbook
It selects your sheet and range B2 but those lines are not important.
The important part is that it creates a public variable "Store"
The Second Macro does two things.
Firstly it moves the cursor to N1 whenever any cell in column N is selected.
This prevents column N being modified.
Secondly if any cell in your data range is selected, it saves the value in that cell in store.
The last macro, stops any cell in the data range being modified.
