Loop ain't working ?

debounce = false

function onTouch()
if debounce == false then
	debounce = true
	for i = 1,100 do
	print(i)
	script.Parent.Parent.BasePlate.Transparency = script.Parent.Parent.BasePlate.Transparency + 0.01
	wait(0.01)
	end
wait(5)
debounce = false
	else
		if script.Parent.Parent.BasePlate.Transparency == 1 then		
		for i = 1,100 do
		print(i)
		script.Parent.Parent.BasePlate.Transparency = script.Parent.Parent.BasePlate.Transparency - 0.01 --here 
		wait(0.01)
		end
	end
end
end

script.Parent.Touched:connect(onTouch)

So simply this should make invisible brick once u touch a trigger, and once u touch it again make it visible so u can keep repeating making it visible and invisible, but it doesn't work all it does it make it invisible and the last part doesn't work. Help ?

end

script.Parent.Touched:connect(onTouch)

well your debounce variable is kinda useless, it should really be used in both if statements also it would look less confusing if you put script.Parent.Parent.BasePlate.Transparency into a variable
