Trying to make gui button open and close a door? [SOLVED]

I'm a beginner so it is most likely very obvious.

if game.Workspace.Cheese.CanCollide == true then
end

script.Parent.MouseButton1Click:connect(function()
	game.Workspace.Cheese.CanCollide = false
end)


function numbertwo()
	game.Workspace.Cheese.CanCollide = true
	end

if game.Workspace.Cheese.CanCollide == false then
end

script.Parent.MouseButton1Click:connect(function(numbertwo)
	game.Workspace.Cheese.CanCollide = true

end)

The Opening Works, it's closing it that's the problem. Cheese = My door btw Can someone please tell me what I did wrong so I don't make this mistake in the future.

collide = true

script.Parent.MouseButton1Click:connect(function()
	if collide == true then
		game.Workspace.Cheese.CanCollide = false
		collide = false
	else
		game.Workspace.Cheese.CanCollide = true
		collide = true
	end
end)

If this doesn't work, tell me in the chat and I'll fix it.

Your problem is that you misplaces your function at the the end. It could be easier.

function openclose ()
local door= game.Workspace.Cheese
if script.Parent.Text== "Open door" then --"Open door" is just a exampe, change it to whatever your button says.
door.CanCollide= false
script.Parent.Text="Close Door" -- Again "Close door" is just an example, change it however you want it.
else if script.Parent.Text== "Close door" then 
door.CanCollide= true
script.Parent.Text="Open door" -- change open door to the text you have in the beginning
end
end
end
script.Parent.MouseButton1Click:connect(openclose)

I wrote this all on mobile and havent tested this myself, there is a high possibility that i mistyped something. But in principle it has to work.
