I'm trying to make a script with ClickDetector but it doesn't work, how do I fix it?

I'm trying to make a script where a button opens door

the code

local part = script.Parent
part.Parent = game.Workspace
local part2 = game.Workspace.Model.Part2
part2.Parent = game.Workspace.Model
local clickdetector = workspace.Model.Part.ClickDetector

local function onMouseClick()
	part2.Transparency = 0.5
	part2.CanCollide = false
end

clickdetector.MouseClick:connect(onMouseClick)

'Part is not valid member of Model' there is no other models in the studio and the Part in the model is named Part

Try:

local part = script.Parent
part.Parent = game.Workspace
local part2 = game.Workspace.Model:WaitForChild("Part2")
part2.Parent = game.Workspace.Model
local clickdetector = workspace.Model.Part.ClickDetector

local function onMouseClick()
    part2.Transparency = 0.5
    part2.CanCollide = false
end

clickdetector.MouseClick:connect(onMouseClick)
