I have taken over the maintenance of a spread sheet which describes the
population of a treatment center. Each resident is assigned an ID code. As
a new resident moves in he/she is assigned the next sequential ID. The ID's
start as 00001. To prevent the dropping of the lead 0's, my predecessor
formatted these ID"s as text. Since the spreadsheet is resorted several
times a day, I want to make sure that the person responsible for maintaining
the spreadsheet does not enter a duplicate ID number. The director of the
center is not ready to change to a database. Any ideas?

Thanks. That helps a lot. But is there a way to have Excel enter the next
sequential number in the series using the parameters i set forth in my
original post?

You could have a 'trigger' cell that, when filled, automatically adds the
next number to the first column, I suppose.
