How do I use tilesets in rpg maker 2003?

I'm trying to use my own tilesets in rpg maker 2003 but it only loads the middle four tiles. Can someone tell me what I need to do? I go to the thing you import with and import the one I want to use. The I add it a tileset in the database. Then I use an event to change the tileset to the one I imported. But when the event is triggered, it only loads the middle four tiles. Am I doing something wrong?
