I've checked lots of tutorials and wikis and checked to see if my scripting was correct and I don't see any error but there must be one. I'm not sure if it's in the gsc or not

dlc3_zone_init()
{

   add_adjacent_zone( "start_zone", "zone_revive", "enter_zone_revive" );
   add_adjacent_zone( "zone_revive", "zone_mp40", "enter_zone_mp40" );
   add_adjacent_zone( "zone_mp40", "zone_jugg", "enter_zone_jugg" );
   add_adjacent_zone( "zone_jugg", "zone_power", "enter_zone_power" );
   add_adjacent_zone( "zone_power", "zone_beer", "enter_zone_beer" );
   add_adjacent_zone( "zone_beer", "zone_speed", "enter_zone_speed" );

I'm not sure what the issue is as I have added the adjacent zones into the .gsc and have added the scripting to the doors and volumes so am not sure of the problem. Help plz.
