OK, first lets simplify the block a little and then fix some actions.
1) Delete Distance 2 along with its scale action and the delete Stretch 2 action from the Deurblad parameter.
2) Remove both flip parameters from stretch actions 1 and 3.
3) Add a scale action to the Deurblad parameter ad choose the door and its arc in the selection set. In the properties of the scale action set it's Base Type to be Independent. Move its action location to the other side of the wall and include this action in Stretch 1. This adds the scaling back but does it without the need for an additional chained parameter and also takes care of the stretch 2 action that wasn't really needed.
4) Add a move action to Distance 1, select the parameters for Flip 2 and 3. In the properties of the Move action set its distance multiplier to 0.5. This will keep the flip action in the middle of the wall.
5) Add a move action to Deurblad, select the parameters for Flip 2 and 3. In the properties of the move action set the distance multiplier to 0.5. This will keep the flip actions in the middle of the door opening.
6) Flip 2 - set its selection to flip everything except Flip 3 and its parameter.
7) Flip 3 - set its selection to flip everything except Flip 2 and its parameter.
Revised block attached.
