Brick dissolving script wont work! (User friendly.) Any codes?

I need some help. I made a script that dissolves any brick called part (Un-Anchored) Whats wrong with it? ** NOTE THE SCRIPT CANT DISSOLVE PEOPLE ON BRICKS WITH THE NAME "PART"**

If hit.Name == "Part" then 

bin = script.Parent

function onTouched(part)
	part.BrickColor = BrickColor.new(26)
	wait(.3)
	part.Transparency = .2
	wait(.1)
	part.Transparency = .4
	wait(.1)
	part.Transparency = .6
	wait(.1)
	part.Transparency = .8
	wait(.1)
	part.Parent = nil
end

connection = bin.Touched:connect(onTouched)

else return end

bin = script.Parent function onTouched(part) if part.Name == "Part" then part.BrickColor = BrickColor.new(0,0,0)

for w = 1, 10 do wait(0.1) part.Transparency = part.Transparency + 0.1 end part.Parent = nil else end end

bin.Touched:connect(onTouched)

im noob
