i have put in some scripts in my comp map for skirmishgla only, however when i put a skirmish china and usa they do not build anything let alone do anthing..
i have put in inner/outer perimeters, waypoints as centerpath/flank/backdoorpath
i have combatzone and skirmish world but they still do nothing

if anyone can give an answer it would be great thanks

If you make custom scripts for a skirmish map for 1 general you have to add the skirmish scripts for the other generals otherwise they dont work...
You can add scripts to player civilian though without problems, usually player0-player7 format is used in the player civilian folder for skirmish maps.

okay so all the scripts i did for skirmish i have to remake in the civilianfolder? :/

Nope, scripting in the civilian folder is a different method of scripting, if you make custom scripts for GLA and you want the AI to play USA also you have to add the USA skirmish scripts to the USA skirmish folder, same goes for other AI generals...
If you add custom scripts to a seperate AI general the other AI generals dont work anymore...
Here  is some more info about player0-player7 scripting...
player0 is the 1st player in a gameroom, player1 is the 2nd etc, it seems a bit odd in the beginning but it is not that hard to grasp...
I used this way of scripting in my Banking Mod, you can find that mod Here
