Oh, he wasn't saying it was a dumb question. He was complaining you said
you were "getting an error". That's not a dumb question, that's a
useless report of a problem. If you don't say what exactly the error is,
we can't help you.

If you want help, the two best things to do are:
  1) Show actual code. 
  2) Show actual, complete tracebacks. 

Having a nice description of what you expect to happen is often nice
too, especially if its doing something "wrong" and not giving an obvious
traceback. Seeing specifically what the wrong behavior is, and you
explaining why you think its wrong, can be invaluable.
