Okay, sorry I wasn't here, I don't use the internet on Sunday.

First off, you CAN'T use more than one chipset per map. To make another map, right click on the name of the game (remember, under the chipset, on the left side) and select "Create New map". That's to make a brand new area. If you want to organize it better, you can drag it to the map you want to be the main map.. Here's a picture of what I mean.
It's picture #1.

To set the doors, make sure to use On Hero Touch to set off the teleport event. Or, instead of clicking "New Event" when you want to make a door, pick "Move Event." It makes an event that moves *you*, it doesn't move an event.
------
To make a chipset work, first go into the DataBase. Click on the Chipsets tab. Set the Max Field Number to be one higher than it currently is. Click on the last chipset space (it will be just a number and without a name.) Now, where it says chipset graphic, select the one you want. It should load. Now, here's the "fun" part... you have to set the terrain for each tile, and its pass/block state.
---------
The reason that editing any chipset screws up your other maps, is because of the fact that the chipsets are SHARED by each map. If you mess with World, any map that uses World will be affected.

Did I answer everything? Again, sorry I wasn't here...
