Erick,

Sorry if I came off as brief. I think that Rick and Gabriel gave you some
good information to work with. And, in case you are discouraged, people
often can help out a lot if you post a snippet of code. I think people get a
little excited/intrigued when presented with code-with-a-bug.

Please do post back if you get stuck again.
