excel 97
I am trying to format a column so that it keeps track of
computer hardware mac addresses. -Each cell must be limited to 17 characters only. -Cells must have 5 visible permanent colons so that users may only enter the remaining 12 letters/numbers. -cells must be restricted to entry of letters and numbers (no special characters). -users must be presented with an error message if they try to leave the cell without entering 12 letters/numbers. -column must not accept duplicate mac addresses. Can anyone give me some direction on how to do this? Adrian Use this form for reples no access to e-mail now |
