Hrm, so in other words my level encoding is not working... back to the drawing board. Thank you for the link. I was using code from usnaviguide on encoding, which was written in Perl but I've translated it to PHP. I'm guessing something got lost in the translation, so I'll use the PHP code on the page you've provided as a guide to fixing it. Thanks much!
