Final Fantasy 12 Level?

I am stuck. I am in the King's tomb, supposedly where there is supposed to be a sword. I am going in...there are 2 doors on each side. One has an inscription, and the other is locked. There is a switch, but every time I press it, 3 zombies appear. On the far end of the board is a teleport light that will not turn on. Does anybody know how to get past this point?
