Whereas, it is recommended to use: $x = $GLOBALS['x']; echo $x; In any event, what I found interesting is: print_r($GLOBALS) if will list all the variables (plus more) in your script. Thus, all variables in your main script are also included in the $GLOBALS array. Cheers, tedd _____________________ tedd.sperling@gmail.com http://sperling.com
