Gaming League Website need fix

Please view my 80% done site at [login to view URL], the orginal disappeared before he finished the job but he gave me all the coding before he left so i need someone to finish this for me. What i need done -fix all the coding errors (i can see the errors on the main page and a little problem with the registration/login system), of course you have to fix other errors that you can find. -add a playoff system (this must be intergrated into the current scheduling and ranking system already done) -add a payment system using paypal and 2CO -Complete intergration with phpbb -additional features (i cannot define now since i cant see the site in action), i basically want a clone of [login to view URL], these additional would be something that you can see missing from my current site.
