Parse error while attempting "Who's online hack"

I edited sessions.php and uploaded it. I now have this error on the control panel page right above where you enter your username and password details.

Parse error: parse error in /www.reefboard.com/cgi-bin/forum/admin/sessions.php on line 209

Anyone know how I can fix this? I can't access the control panel now.

I fixed this by deleteing the sessions.php file and reuploaded the old "unhacked" one. Everything seems to be working now.
