File Download and Header

Hello,
I have a link on a page(A) that calls another page(B) that reads a
BLOB from a DB and uses header() fields to display a file save dialog
box. This all works. But nothing else on page B ever gets
displayed.Page A Stays up:

header("Content-Type: $filetype");
header("Content-length: $filesize");
header("Content-Disposition: attachment; filename=$filename");
header("Content-Description: PHP Generated Data");
header('Pragma: private');
header('Cache-control: private, must-revalidate');

But there is also other stuff on this page(B) that I want to display.
I am using PhpEd and I step through page B to the end but B never
shows.
Any suggestions?
Thanks
Mike
