My float script isn't working, the script looks good to me :(, what i did wrong?

I created a float script that when the player touch the brick, he will float, and when he isnt touching the brick, he will stop floating, but i dont know why he isnt working, what i did wrong?

player = hit.Parent
torso = player.Parent.Torso
human = player.Character.Humanoid
bin = script.Parent

Activated = false

function onTouched(hit) 
    local d = hit.Parent:GetChildren() 
    for i=1, #d do 
Activated = true
if (bin.Touched == false) then

bin.Touched = true
for i, a in pairs(torso:GetChildren()) do
    if a.Name == "FloatV" then
    a:Remove()
    end
end
bv = Instance.new("BodyVelocity")
bv.Name = "FloatV"
bv.maxForce = Vector3.new(0,math.huge,0)
bv.velocity = Vector3.new(0,0,0)
bv.Parent = torso


else bin.Touched = false

for i, v in pairs(torso:GetChildren()) do
    if v.Name == "FloatV" then
    v:Remove()
    end
end
end
Activated = false
        end 
    end

script.Parent.Touched:connect(onTouched)
