How to add position to the part?

hello there, i am beginner scripter, and i have a problem.

basically i want to add position to the current position of the part
example: from 0,0,1 to 0,0,2 and from 0,0,2 to 0,0,3

solutions i tried:

clone.Position += Vector3.new(0,0,1)
clone.Position = clone.Position + Vector3.new(0,0,1)
clone.Position = Vector3.new(0, 0, clone.Position.Z+1)

^^all those solutions i found on internet and some i tried by myself

if you need some screehnshot or video showing the problem, i can show you if needed

All of these should work, I don’t see the problem. First one is the most efficient though.

oh well the problem is not at position, sorry
