LiveCode server and library stacks

[Ralph DiMola]

I'm writing a web service. I'm trying to activate a library stack using this
code:(line numbers are included just in email)

15:if there is a file ("lib/DB_Library.livecode") then
16:  start using stack ("lib/DB_Library.livecode")
17:end if

the code finds the stack file but it won't "start" I'm getting this error:
row 16, col 9: Chunk: can't find stack
  row 16, col 1: start: can't find object
  row 15, col 1: if-then: error in statement

Where am I going wrong?
