As you yu can read above i got a little anoying Problem. I connectet DweBREntrance01 with DweLevler01 like http://www.creationkit.com/Bethesda_Tutorial_Traps_and_Prefabs shows but it only opens but never close again. I found only a open scribt in
DweBREntrance01. Do i need just to add a close script and when, how i do it or must i rewrite the open script.

Does nobody know something

There has to be a script for it because closing doors is used in the game, finding it is the real challenge. If I come across it I will post. You could try looking at doors in the game that close. Mage College quest line and Companion quest line both have sections where a door closes locking the player in a room, but they are both tied to activating something. Maybe if you found those scripts in the CK you could find a way to automate the closing.

For an actual door you don't need any scripts, you just have to set the lever as the door's activate parent. The problem is that you're not using a door, you're using an activator. And I think that activator was never meant to close once it opens. What you'll have to do is modify its existing script to add extra states and conditionals for it to be able to close, along with setting up the close animation as a property.

Thx for the answers. Looks like i have too deal with Papyrus. Wish me Luck
