Eh I don't mind helping.
Anyways.
Press F8 to go the event layer. Then in the Event Commands window, double click and open the three or four event pages. On the first page, you see a Switch Operation command. On that, you see an option, Specific Switch with a number next to it, and an arrow. Click on the arrow. You'll see a whole pile of switches. Pick one, but give it a name.
This will be important so that you don't re-use the same switch again. Once you've given the switch you want to use a name, click it, then click Ok. So that's done.
Now make a new Page. There's an option for that at the top. On this new page, look at an area that has Preconditions on it. Under it check the first box for switch. You'll see an arrow like before. Click it and find the switch you just named. Then click Ok. On this page, MAKE SURE the person's graphic is empty! If it's a treasure chest or a door, make sure it is open.
Need pictures too or is this good enough?
