Lift Animatioon not playing no clue why ?

Hello Everyone.

I have a problem with a Weight (Tool) i made 2 Animatiions 1 for Action 1 for Idle

My problem is that the idle animation plays like 2 secoonds and the lift animation does nothing.

(i'm new in LUA coding so sorry :) just knowing php)

Here is the code in the Tool.

local db = false
local tool = script.Parent
local plr = tool.Parent.Parent
local character = plr.Character
local strengthPerClick = 5

local anim1 = tool:WaitForChild("LiftAnim")
local animtrack1 = character.Humanoid:LoadAnimation(anim1)

local anim2 = tool:WaitForChild("IdleAnim")
local animtrack2 = character.Humanoid:LoadAnimation(anim2)


tool.Activated:Connect(function()
    if not db then
        db = true
            warn("Tool used")
        animtrack1:Play()
        plr.leaderstats.Strength.Value = plr.leaderstats.Strength.Value + strengthPerClick
        wait(1.5)
        db = false
    end
end)
tool.Equipped:Connect(function()
    warn("Tool Equipped")
    character.Humanoid.WalkSpeed = 0
    animtrack2:Play()
end)

tool.Unequipped:Connect(function()
    warn("Tool Unequipped")
    character.Humanoid.WalkSpeed = 16
    animtrack2:Stop()
end)
