I added a vehicle to my map but when i tested my map there readed that there is the vehicle in command post, but when i go there its not there. HELP ME!

I don't think that you set up the memory pools right. It is in the Lua, somewhat at the bottom. It will say set memory pool size. If it was a xwing you were trying to put in, you would have to type "SetMemoryPoolSize("EntityFlyer", 10)
If it was a hover vehicle just replace Flyer with Hover. 10 is to represent the number of that type of vehicle you have in the map. If you had 5 xwings and 5 tiefighters the number would be 10

Thanks now i can get my x-wing to appear! thanks so mutch!
