Perhaps I misunderstood. I thought from this and your other message that you already had the function created to get a volume serial number. If you don't have that function, then sk33v3's link is what you need; download the code from there. If you have the function in your program, and you're getting the error above, then I think you need to explain a bit more what's going on (show us the code where you're getting the error).
