Headers sent by - need to clear screen - help me

I don't know if I'm wording this right. I have a display_error function in PHP that I want to generate a screen with some information about the error, send us email, etc. The problem is that sometimes it's called after the headers have been sent and in the middle of a page. Is there a way to 'clear' the screen and putup the error stuff? Thanks! Mike ****************************************************************** This communication is for informational purposes only.
