php question

Sorry, searched the whole site looking for the correct way to e-mail someone with a problem. also cc'ed to my php guru and mentor, John A. Trying to go from a php script to a cgi-driven data base in this fashion: header("Location: http://www.sierratimes.com/cgi-bin/wh/newspro.cgi?generate"); exit(); It comes back with: Warning: Cannot add header information - headers already sent by (output started at /home/johnson/public_html/03/batch/news_cat.php:33) in /home/johnson/public_html/03/batch/batch.php on line 106 Yes, I even tried adding the: session_write_close(); function - nada. news_cat.php is an include file that I call several times during a session, and to the best of my knowledge, it's doing nothing with header info (it simply builds a string for an HTML drop down menu). I looking in the documentation area in php-ville and saw that 'php jury' is out on header function causing funky errors. Well, I'm getting them here and remain clueless as to what to do. background: the url: http://www.sierratimes.com/cgi-bin/wh/newspro.cgi?generate builds .txt files from the main database that are used as ssi calls all over this site. I've successfully written to the main data base. Only thing remaining is to 'give the order' to work from the new data. And as Murphy's law would have it, this is where I'm stuck. help! J.J.
