BleepingComputer.com: C&c Generals: Zero Hour, World Builder Questions

I have been getting into using the world builder program that comes on the game disc. I figured out how to get a skirmish map, and the AI working. But in the skirmish maps, i cant figure out how to make units i put in the map controllable by me. For example, i put a pathfinder in the map, when i play the game he is still in the map, but i can not use him. I have tried changing the ownership around. Is it just not possible to do in a skirmish map? All the tutorials i have read for it say nothing about if you can or cant. Any help??

I'm new to the program, and its the most difficult map editor i have ever used, so any other words of wisdom would be helpfull!
Thanks!

1.hm ive never tried to put units in a map before...
try looking at the properties of the stuff.

2.hardest map editor? try UnrealEd... it makes my head explode!
