Loop not 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 ?

debounce = false
Vispart = script.Parent.Parent.BasePlate--to change if you want
vison = false
script.Parent.Touched:connect(function(touch)
if debounce == false then	
	if vison == false then
		debounce = true
		vison = true		
		for i = 1,100 do
			print(i)
			Vispart.Transparency = Vispart.Transparency + 0.01
			wait(0.01)
		end
	elseif vison == true then
		debounce = true
		vison = false
		for i = 1,100 do
			print(i)
			Vispart.Transparency = Vispart.Transparency - 0.01
			wait(0.01)
		end
	end
		wait(1)
		debounce = false
		print("Ready to fire again!")
	end
end)

You basically had the logic of your function set up wrong.
