triwbass, trying to read your post made my head hurt.  Please try to use commas, periods and capital letters at the beginning of sentences.  It makes it much easier for others to read, and might get you some decent responses.  Most potential responders will simply ignore your post if you're too lazy to use proper punctuation.
