Wrong! Always post code to this forum. Code on pastebin will not be available in a few weeks so the content of this thread is lost. We only look at code that is posted here. The excerpts we currently see are probably not relevant. So if you want us to help you, follow the rules of the sticky post "How to use this forum - please read".
