That did it! I wonder if there is a way, then, to have it work even if the variable is initialized after it is echoed. I was actually trying to do this to pass values in another script. I'm writing some code that has to do with storing and retrieving images in mysql. I'm having trouble passing image information (the kind needed for getimagesize( ) to work) and I can't get session variables to initalize in that either. More experimentation with echo (and other code) placement needed. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
