ok so now there is another problem. so i put all the info in my mapname.gsc and then i did everything that you guys told me to do. my zombies arnt spawning in the start_zone and its just skipping throught the rounds. and i even watvhed a video on how to zone and what to put in radiant but my zombies arint spawning anymore if you can help thank you. here are the pics on to see what ive done wrong.
The zones-----------------------------------------------------








The Zombies--------------------------------------------------

start_zone_spawners


zone1_spawners


zone2_spawners


the script_vectors for the doors leading to the next zone

enter_zone1


enter_zone2


so ya the zombies arnt spawning the the start zone so if you could help thank you so much.

You commented the new lines you added. The "//" in front of a row of text means it is a comment, and not part of the script. So you have to remove the "//" from the lines you added to make them work.

no its still not working it just went to round 2 then 345678910 but it just skips i did what you said

Your start_zone worked before, right? Did you change anything to that zone?

check if this is in your mapname.gsc:

	// Initial Zone(s) -- Zone(s) You Want Activated At Map Start
	zones = [];
	zones[ zones.size ] = "start_zone";
	level.DLC3.initialZones = zones;

ahhh yes it was initial_zone cause in radiant it was start_zone so i changed it thank you so much bro
