Hi Jorge,
your best bet is to post the app/dct/data here so someone can have a look - I'm sure it will be something very basic.
As it sound like your are just starting out I strongly recommend also buying the Nettalk Web Tutorial book. It will just make going from beginner to intermediate and advanced so much faster. It is an extra cost but will pay for itself 100 times over when you start building amazing apps!
Cheers,
Kevin
