formbuilder: where do you put a redirect statement to redirect you to another page after processing?

I've tried in the form that calls the dataobject page, in preprocess and postprocess functions and none work. They all throw the error "Cannot modify header information - headers already sent by..." My page has some html in it before the php code for formbuilder. If I take that out it works but I need that in to format the page properly. If I can't have that in, I might just scrap using FormBuilder. Thanks for any ideas __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
