A little problem

[auto]

I've decided to do away with the vB icons and change them to text...

you can see how on top it says Free Registration! in red and all other links on the right.

I tried to make it so that only guests will see the Free Registration! link.

In global.php I added this:

PHP Code:

if ($bbuserinfo['userid']!=0) {
    $registertext=" ";
} else {
    $registertext="<A HREF=\"register.php?s=$session[sessionhash]&action=signup\"><b><font face=\"verdana\" size=\"1\" color=\"red\">Free Registration!</a></b></font>";
    } 


But for some reason the text doesnt dissappear for the logged in users. What am I doing wrong?

thanks
