Becuase you use annoying non-words like "plzzz", "ne", etc., I refuse to even read your post.
Also, because you posted hugely, ridiculously, unessary wads of code, I refuse to even read your post.
Somebody else may be less of a butthole than I, but there are at least some here who share my views. It's in your own best interest to make your post appeal to the widest audience possible.
