Prop_door_rotating problem

Now, i made an npc_gman, scripted_sequence and a door. Classic Gman scene. So when the player touches a trigger, i trigger the scripted_sequence to make gman walk to it, and the door to open. But when the door opens, it closes while it’s half open. I have no outputs telling the door to close, and the door itself has no outputs or inputs. Is this a common problem? And does anyone know how to fix it?

There is a thing called Door Dely or Door Close or somthing on the entity menu, set it to -1 and it will never close otherwise set it to how many seconds you want it to saty open for
