You might be someone who could benefit from the "List" feature in xl 2003.
Enter "List" or "Create a List" in help and read up on it.

....A new row is inserted automatically in the List when you enter
data in the last row of the "List" ( the last row has an * in it).
....Assuming you list starts in A3 then enter this formula in A4:
"= A3 +1" and fill down.
....Then when you fill in data in any cell in the "Last" * row an
incremented invoice number will automatically appear in column A.

I have a list of invoice details with the inv number in col A (sequential
starting 10001). Is it possible to make a control button that would add a new
row at the botttom of the list and automatically give it the next inv number
in col A?
