Welding a door doesnt work

Hi, so i’m currently trying to weld a TWEENING DOOR and the problem is, that when the door starts to tween, the welds just stop working (They dont disappear, they just dont work for the tween). Im using the normal welds, I also tried WeldConstraints, but that didnt work either.
Thank for reading (and helping)!

Yes, that is the problem with tweening with welds. If you are using normal welds, you can tween the CFrame of the C0, which will move everything.

When you tween the door are you tweening its CFrame or Position?

The problem is, that I had to use CFrame instead of Position, thank you for trying to help!
