Sequential numbering

[srsev]

I am trying to create a macro that will number my cells automatically beginning with ABC-001-1. For instance, (A1) is ABC-001-1. When i reach ABC-001-6 (A6), I want (A7) to move to ABC-002-1, (A8) ABC-002-2, (A9) ABC-002-3 all the way to ABC-002-6 (A12). Then in cell (A13) i want ABC-003-1 to ABC-003-6 (A18). See example below. Thank you so much for your help

Try this formula in A1 copied down:

="ABC-"&TEXT(INT(((ROWS(A$1:A1)-1)/6))+1,"000")&"-"&MOD(ROWS(A$1:A1)-1,6)+1

That worked perfectly Andrew. Thank you so much for your help
