Falling Stairs

I have a set of stairs that are higher than the player can reach. I want to make it so when I activate the first step, all the steps fall to floor level and then rise again. I got the first step to lower to the floor, but all the others only lower slightly. How can I get it so they all meet the floor at the same time?

Did you try using dummy (helper) sectors? Also, what port are you using?

I'm using it on standard DOOM 2 cuz I want it to be playable in all forms. Plus, I wanted to start basic.

Anyway...how exactly can the dummy sectors help me in this situation?

I'm just confused as to why the higher steps only seem to go about halfway down as opposed to all the way to the floor...

note: I made the dummy sectors really large so you can easily see what's going on. Obviously in your wad, you can make them smaller. ;)
