Can someone tell me why my iron maidens door doesn't open?

[LulleBulle]

Maybe works this

AddBodyImpulse("iron_maiden_2_leftDoor", -900, 0, -900, "world");

AddBodyImpulse("iron_maiden_2_rightDoor", -900, 0,900, "world");

Thank you, worked prefect. Never thought that I should add more power, since it didn't move at all I thought something else was wrong..
