thanks for the advice mate... really... i ask for help when i need it... like i said, and not to appear rude... if you can't/don't feel like/won't help i don't understand what's with the replying... if i wanted to be told off then i wouldn't be writing don't you reckon?

Try sitting down with whatever books you're provided the Internet as refrence and actually learn something about what you're doing rather than asking other people to hand you answers on a silver platter.
