Development thread moved to the dev area for better exposure.

It might help if you told us (well, the developers in the house, at least) what you're trying to accomplish and what's going wrong. It's good to include the relevant code snippets (of course) but that doesn't really tell us anything about the problem.

Pro-tip: you can use [code]...[/code] tags to make your code a bit easier to read.
