How would you make a block that transparent go opaque and back transparent again?

So, I have a block with the transparency of 0.5, But I would like it when you click the block the transparency goes to 1.0 then if you click the block again it will return back to 0.5

Thanks for y'all's help!

First put a ClickDetector and BoolValue into your part, and insert this script.

local clickdetector = script.Parent:WaitForChild("ClickDetector")

clickdetector.MouseClick:Connect(function(FirstClick)
	if script.Parent.Value.Value == false then
		script.Parent.Transparency = 1
		script.Parent.Value.Value = true
	else
	if	script.Parent.Value.Value == true then
		script.Parent.Transparency = 0.5
		script.Parent.Value.Value = false
		end
	end
end)

Accept my answer if this helps!
