You should put this entire post into a reply on your first post, then delete this one. This will help keep everything on one page, and people will be more likely to read through that mess of code to help you (although such large amounts of code will put off most people anyways...).

I dont know how they would help me with my problem with one little snippet of code thats why i posted everything here because in the other one it only had where i had the problem but its linked to everything else.

You could post everything from this post as a reply in your first post. That's what I was getting at.
