Map Size and Camera Bounds

[Far Aldazar Din]

I'm trying to make my map bigger, because I realize that it is to small. I don't just want to make a new map, because I have alot of stuff on it. I'm messing with the Map Size and Camera Bounds and am not sure how to make it bigger. Can someone help me?

go to scenario, mapsize and camera bordes, and check "modify mapborders" then you can simply make it bigger by clicking the arrows
