moving my big door? (cant solve)

open = false;
while true do
wait();
local PlayerNear = characterIsInRange();
if PlayerNear == true and open == false then
play("open",1);
play("bars",60);
wait(3)
moveBars(-0.5);
wait(2)
play("door",0.8);
moveDoor(0.0);  --move on -z axis
wait(8)
moveDoor(0.9);  --moving on +x axis
open = true;
end;

i don't know how to move it back i tried but i don't understand what i am doing wrong

i found out it can only ONLY move on the x axis and not much i can do to make it move on the z axis other then remake the whole script and im not doing that

Um, I agree with Dragon, But also I saw in the script you have "Sideways" and "Backwards". Well, if doors are moving sideways by 0.9 , then wouldn't you want them to move BACK again -0.9?
