[ANSWERED] Why does my friend's animation not work - I have action enabled?

All in all, my friend has made at least 5 animations for a tool, and when you click it makes you play the animation. He set the animation to action, and the script runs my animation perfectly. But when we change the AnimationId to his animation, it doesn't work. Does anyone have any idea why this doesn't work? My script:

AnimationId: rbxassetid://5357281801

local spells = {
    "lumos",
    "nox"           
}

local activeSpell
local tool = script.Parent

repeat wait() until game.Players:GetPlayerFromCharacter(tool.Parent)
local plr = game.Players:GetPlayerFromCharacter(tool.Parent)
local db = false
local cooldown = 3

--possible future stats     local mpc = plr.leaderstats.MPC.Value

tool.Activated:Connect(function()
    if not db then
        db = true
        local anim = game.ReplicatedStorage:FindFirstChild("CastWand")
        local animtrack = plr.Character.Humanoid:LoadAnimation(anim)
        animtrack:Play()
        if activeSpell ~= nil then
            print("Working!")
        end
        wait(cooldown)
        db = false 
    end
end)

game.PlayerAdded:Connect(function(player)
    game.Players.LocalPlayer.Chatted:Connect(function(msg)
        local spell = string.lower(msg)
        if spell == #spells then
            activeSpell = spell
        end
    end)
end)
-- if any future stats
--[[ tool.Activated:Connect(function()
    if mpc == 0 then
        mpc = mpc + 1
    end
    if estore == 0 then
        estore = estore + 20
    end
    if cooldown == 0 then
        cooldown = cooldown + 1
    end
end) ]]
