Conections are easy. You need to set them right for the 2 connected maps. The "Zero Out" means leveling the maps out (You need to do both maps seperate, or it doesn't work). Experiment with putting numbers there (They differ depending on where te connection is... I think if the Connection is up, a positive number makes the connection go right, and a negative makes it go more left)... It is easy to do, but hard to explain (like Mapping in general...)
