Help with Post code format

Hello

I was wondering if it was possiable to format a cell so that it only shows the letters that i wish for example:
if my post code was bt53 i only want it to accept "bt" and nothing else, so if i typed in bg53 it wouldnt allow it?
can this be done?


Many Thanks
Aaron

You only want the cell to accept bt? Not bt53 or bt54 or ????

Do a search on data validation, that may be what your looking for. It only allows certain values in cells based on lists you supply.
