TouchJSON not working to retrieve data on iPhone

I am trying to use TouchJSON to retrieve data from a php page with json output. I have followed the same steps as an example project I开发者_开发百科 downloaded from and it still isn't working. When I select the section containing the data from my main menu the app crashes. I am including my view controller implementation file. Thanks, enbr. http://pastie.org/pastes/1070273

I have fixed my problem.
