Hmm. You dump almost 600 lines of PHP. Can you elaborate on which functions are causing problems. I mean, narrow it down for us please. Do you get any errors? If so, what are they?

Are you using a form? If so, let us see it.
Are you retrieving data from a DB to feed into this class? Again let us see what you're doing.
