How to target result of Form call to php file into different frame??

Hi overthere! I'm still busy getting my search engine up and running ;-) If there are any interested to use it, I can send you the implementation!!! It's working roughly now. I got it up and running all thanks to the splendid input of the people of this amazing mailinglist!!! But still some tuning stuff left to deal with;-¤ I have my search site devided into two frames, the "header" containing the search text field with button, the "body" displays the search result table. I call the "searchDB.php" script via the search form but the search result should be dumped in the "body" frame. How can i 'target' the result of the php-database-search into an other frame? Any trick, tip or irresistable hint is very welcome!!!!! FB. Yoeri.
