2 levers opening one door?

[BossGengar]

Hi! Okay so I'm making a personal dungeon-crawling map. I want two levers from opposite sides of the map and when both of them are attacked it opens a gate. I have no idea how to do this. I know it may have something to do with variables, but I don't know how to do those kinds of triggers. Can someone please give me some advice?
