Please help me I'm just new to scripting and please put the correct script for me please!!

local prev local parts = script.Parent:GetChildren() for i = 1, #parts do if ((parts(i).classname == "Part") or (parts(i).className == "Handle") or (parts(i).classname == "WedgePart") or (parts(i).classname == "Seat") or (parts[i].className == "WedgePart" or (parts[i].classname =="TrussPart") or (parts[i].className == "VeichleSeat" or (parts[i].classname =="UnionOperation") or (parts[i].className == "SkateboardPlatform")) if (prev ~= nil) then local weld = Instance.new("Weld") weld.Part0 = prev weld.Part1 = parts[i] weld.C0 = prev.CFrame:inverse() weld.C1 = parts[i].CFrame:inverse() weld.Parent = prev parts[i].Anchored = false end prev = parts[i] end end wait(3)

Just use qPerfectionWeld by Qwerty. It's simple and works for everything.
