Try this:

=$B$6&"-"&A15&"-"&B15&"-"&TEXT(C15,"000")

Does that help?

I am wondering how to make cells in a formula automatically 4 digits long?
The actual formula I am using is "=$B$6 & "-" & A15 & "-" & B15 & "-" &
C15".
If the C15 cell is say, "003", in the formula it comes out "3". I need 3
digits for the last part of the whole formula in the column. Any help
would
be greatly appreciated! Thanks!
