I am trying to use custom formatting in excel to show the following format for account numbers that I use:
E-9511-I200-100-610
The E is always constant, but the place where the I is typed can be either I or S or A.
I can format for everything by the variable letter. So far, I have come up with "E""-""####"-"###"-"###"-"### but I don't know how to complete it to accept the variable letter. Please Help!
