In short, you're trying to do something that is very well-documented and has been done countless times by tens of thousands of people, so it should work very well. If it's not, you're going to need to provide some more information.
For starters:
1) What is it doing when it's not working?
2) What, exactly, are you trying to do?
3) What have you tried so far?
4) What have you changed in the configuration to try to make it work?
We might seem useless in these here forums, but at least you can look at what you're working on. We have to use our imaginations
