when i weld an Gun without any unions to "Blue", it works properly. https://gyazo.com/193874fb51578c4f15e1571ec65188ee

when i weld an Gun with unions to "Blue", "Green" moves, but blue / gun stays in place. https://gyazo.com/d5ecd46e1bdbe5b00220cc25db7ff826 How do i fix this? Whats wrong with my script? Am i welding unions incorrectly?

local Speed = 0.3
 
--- constantly lerp the blue part to the target CFrame.

thanks for your help.
