I'm going to give you the benefit of the doubt and pretend your actually new and don't have a clue - few people will accept Paypal as a payment method due to its extremely reversible nature (see link:
https://bitcointalk.org/index.php?topic=14632.0). Those that do will not deal with newbies, but rather established traders who have built up a reputation over time. In light of this, you're really unlikely to get anybody willing to take you up, so I would suggest if you do want to trade that you try something like localbitcoins and deal in bank transfers/moneypaks etc.
