could i have some help with the eating animation with tool/food in hand?

So. me and a group are making a restaurant game but i want it that if the player has the food they click the left mouse. And the animation only plays if the burger is in hand. But the animation doesn't move. here is the script:

local animation = Instance.new("Animation")
animation.AnimationId = "https://www.roblox.com/Asset?ID=1069941509"

local trackanimation = nil
local playability = true
function playAnimation(AnimationSource)
    if playability == true then
        local plr = game.Players.LocalPlayer
        trackanimation = plr.Character.Humanoid:LoadAnimation(animation)

        trackanimation.KeyframeReached:connect(function()
            print ('Working')
        end)
        trackanimation:Play()
    end
end

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
local waituntilback = script.Parent.Parent.Hamburger.Equipped:connect()

script.Parent.Parent.Hamburger.Equipped:connect(function()
    if not script.Parent.Parent.Hamburger.Equipped:connect() then
        playAnimation(waituntilback) else
        playAnimation()     
    end
end)

is something wrong about it?
