switch(playerid)
{
case DualRoom1: <-- 694
DualRoom1 = -1;

case DualRoom2: <-- 697
DualRoom2 = -1;

case DualRoom3: <-- 700
DualRoom3 = -1;

case DualRoom4: <-- 703
DualRoom4 = -1;

}

This script says if( playerid= DualRoom1){DualRoom1=-1} etc. So to work you need to make a playerid = DualRoom1/2/3/4
