Gun so longer is shooting help? (UNSOLVED)

Well once i added lines (4-13) the gun no longer would shoot. I am trying to make it to where if a player is Anchored another player would shoot the (FlameThrower), and it would Unanchor the player and it would cause no damage.

local debounce = false


function onHit(hit)
    local human = hit.Parent:findFirstChild("Humanoid")
    if (human ~= nil) and debounce == false then

                debounce = true
game.Workspace.FlameThrower.BlowDryer.HotAir.Anchored = false

                debounce = false
    end
end


script.Parent.Touched:connect(onHit)


print("Flamethrower script loaded")

Tool = script.Parent

shooting = false
reloadtime = 0

colors = {1, 208, 45, 11} 

function fire(v,a)




    local missile = Instance.new("Part")

    local vCharacter = Tool.Parent

    local head = vCharacter:findFirstChild("Head")
    if head == nil then return end


    local spawnPos = head.Position
    spawnPos  = spawnPos + (v * 10)

    missile.Name = "HotAir"

    local dx = (math.random() - .5) * .01
    local dy = (math.random() - .5) * .01
    local dz = (math.random() - .5) * .01

    missile.CFrame = CFrame.new(spawnPos, Vector3.new(dx,dy,dz))
    missile.Size = Vector3.new(2,2,2)
    missile.Velocity = v * 80
    missile.BrickColor = BrickColor.new(colors[math.random(1, #colors)])
    missile.Shape = 0

    local fire = Instance.new("Fire")
    fire.Color = Color3.new((s/255),0,a)
    fire.SecondaryColor = Color3.new(s/400,0,a)
    fire.Parent = missile

    local force = Instance.new("BodyForce")
    force.force = Vector3.new(0,98 * 8,0)
    force.Parent = missile
