sessions

Hi, I have problems with php's session handling. The php parser inserts the session_name=session_id string twice in the place of <?=SID?> everywhere, and this way all my scripts became unusable. these scripts worked some time but doesn't seem to do so now. I upgraded php some time ago, but I realized it just now that my old working scripts don't work on my homepage. for example: this is in the .php file: <a href="something.php?<?=SID?>"> and this is what the browser gets: <a href="something.php??Session_Name=Session_IdSession_Name=Session_Id"> thanx in advance, Gabor
