Just some more general thoughts about your slightly vague question:

You got six replies:

1. "What does that mean?" (Anonymous Monk)
2. "You need to give an actual example..." (stevieb)
3. "Just how are you 'passing' "v=33" as an argument?..." (AnomalousMonk)
4. "Could this be a quoting problem?" (ww)
5. "Argument to what?... " (Laurent_R)
6. "...you want actually something like this?..." (karlgoethebier)

It is considered as good practice in such a case to give some feedback, like answering the questions, updating your OP with a more precise question etc.

Best regards, Karl
