Sessions

Greetings from San Diego! I call session_start() on all my pages and then <? echo session_id(); ?> and everything is the same from all the pages. However if I stuff a variable into $_SESSION it's never transferred between pages. So if I do a <? $_SESSION["Username"] = "Brian"; ?> and then go to another page and say <? echo $_SESSION["Username"]; ?> it comes back blank. It doesn't seem to matter if I enclose the Username in double quotes """ or single quotes ''' or nothing; I have no data. But like I said, the session id is being passed around just fine. Someone help??? Thanks, -brian Brian D. McGrew { brian@visionpro.com || brian@doubledimension.com } --- > YOU! Off my planet!
