How do you make a door on a crate open

[Shadowblind]

Im trying to make the doors on a crate 100 x 128 open, I have the door set for D1 Open Stay. When I click on it it makes the opening door sound, but the door remains shut. What else must I use?

By you description I'm assuming that the floor of your crate sector is 128. So make the floor\ceiling height of your door both 128.

No, the crate is 100 up. The roof is 128. That would make the door go above the crate.

You can't make doors that have space above them.

But what you could do is make the side of the crate lower when the player presses it.

Good idea... But somethings wrong. About halfway through the level, the items and monsters I placed have stopped appearing...whats going on?

Did you check their tags? You may have accidentally set the tag on one so it's multiplayer-only or doesn't appear on the difficulty setting you're using to test this map. In Doom Builder (which I'm assuming you're using), when you place a thing with tag settings, those tag settings are remembered until you place a thing with different ones.

I hope I explained that well enough.
