Why doesn't my door script work?

I'm using a click detector, so when a player touches a door, the door will have 1 transparency and wont be cancollide? my script is:

script.Parent.MouseButton1Click:connect(function(click) -- If the door is click do:
script.Parent.Parent.Transparency = 1 -- Sets Transparency to 1 so its invisible
script.Parent.Parent.CanCollide = false -- Sets CanCollide to false so its gothrough
wait(5) -- Door will open for 5 seconds
script.Parent.Parent.CanCollide = true -- Set CanCollide back to true
script.Parent.Parent.Transparency = 0 -- Change the transparency back to 0
if script.Parent.Parent.CanCollide == false then -- If CanCollide is false then
script.Parent.Parent.CanCollide = true -- Set CanCollide to true if its at false
else -- If CanCollide was true already
print("CanCollide part works") -- This is what "game" says if the CanCollide part of the script works.
wait(0.1) -- Wait 0.1 seconds
if script.Parent.Parent.Transparency == 1 then -- If its at 1 then
script.Parent.Parent.Transparency = 0 -- Set it to 0 if its at 1
else -- If the transparency was 0 already
print("Both parts work, Script works") -- This is what "game" says after it checks the Transparency
end -- Ends the first "if"
end -- Ends the seconds "if"
end) -- Ends the whole script

NOTE: If you know, please just dont ignore this, give all what you've got.

Simplier version:

script.Parent.MouseButton1Click:connect(function(click) -- If the door is click do:
script.Parent.Parent.Transparency = 1 -- Sets Transparency to 1 so its invisible
script.Parent.Parent.CanCollide = false -- Sets CanCollide to false so its gothrough
wait(5) -- Door will open for 5 seconds
script.Parent.Parent.CanCollide = true -- Set CanCollide back to true
script.Parent.Parent.Transparency = 0 -- Change the transparency back to 0
end

I think you need to inset a ClickDetector into the door, if you haven't already :)

What are you trying to do? Make the door transparent and cancollide if the brick is clicked??

Your script is way more coded then it needs to be

function Click()
script.Parent.Parent.Door.CanCollide = false
script.Parent.Parent.Door.Transparency = 1
wait(5)
script.Parent.Parent.Door.CanCollide = true
script.Parent.Parent.Door.Transparency = 0
end
script.Parent.MouseButton1Click:connect(Click)
