session_register() in a function...again

Hi all, I saw the post about placing a session_register() in a function and about how the var that you want registered needs to be global... My question is, how much more global does it need to be than the following? function check_something() { global $var_to_reg; if($something) { session_register("var_to_reg"); } } I even set the var outside the function (in global scope) and tried registering it inside the function...to no avail. The above will NOT start a session and obviously not register the var. If I place the code in the global scope it does. Any ideas? PHP4b3 Apache 1.3.9 -Dave
