Assuming that $_GET['style'] existed without testing for it was the first thing that should've been looked at. In order to make maximum use of this mailing list, it's really helpful for us to see the _actual_ code you're using, rather than fake code. Your fake code had no problems, so we weren't able to provide you with a solution, but it sounds like your real code had the error that caused the problem. Even in your latest post, you put this: () What's with all of those double-quotes? More fake code, or is that actually what you have in your code? ~Ted -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Does :

My mistake. I meant to type echo $strLow; not echo $thisStr; in my
post.
