When Part is touched the tool gets removed, but doesn't add 10 gold, and doesn't print text? [closed]

The part that works is the part where it gets rid of the item in the backpack on touch but doesn't give gold for it (a sell weapon button). And it also doesn't print the message saying "you bought this for 100" or "you don't have that weapon"

local debounce = false



function getPlayer(humanoid) 

local players = game.Players:children() 

for i = 1, #players do 

if players[i].Character.Humanoid == humanoid then return players[i] end 

end 

return nil 

end 



function onTouch(part) 



local human = part.Parent:findFirstChild("Humanoid") 

if (human ~= nil) and debounce == false then



debounce = true



local player = getPlayer(human) 



if (player == nil) then return end 



user = game.Players:findFirstChild(human.Parent.Name)

local gold = player:WaitForChild('leaderstats').Gold

    if player.Backpack:findFirstChild("Wooden Sword") ~= nil then



    m = Instance.new("Hint")

    m.Text = "You sold your Wooden Sword for 10 gold!" 

    m.Parent = player

    player.Backpack:findFirstChild("Wooden Sword"):remove()
    wait(2)
    gold.Value = gold.Value + 10
    m.Parent = nil

else

    m = Instance.new("Hint")

    m.Text = "You need the Wooden Staff to do this."

    m.Parent = player

    wait(3)

    m.Parent = nil

end



wait(2)

debounce = false

end

end
