Ok. So I have one room where you are upstairs. When you stand on the stairs, I want to direct warp to a room I have set as downstairs. In the original tileset, the stairs were set to cave walk down, but I could not get them to take you to the downstairs room, they took you to a cave instead. So I changed them to Direct warp and went Data -> Tile warp and told it the screen where I wanted it to warp you to, and I am still appearing in the cave. What am I doing wrong?

Plus I have another problem. The downstairs screen is screen 10 and upstairs is 00. When I make screen 10's pallete the same as screen 00's, screen 00's transparent layer is not coming out right. What am I doing wrong?
