I'm currently having an issue with making a reload animation play, could anybody help me fix it?

I'm making a game, and the gun I've made works fine, however, the reload animation is the only thing that doesn't work. Does anybody know how I can fix this?

Here is the script to play the reload animation, there are variables for the reloadTrack and reloadAnim, and in the handle of the gun, there's a sound named 'Reload':

tool.reload_sound:Connect(function()
    if reload_sound:Playing() then
        reloadtrack = script.Parent.Parent.Humanoid:LoadAnimation(reloadAnim)
    reloadtrack.Priority = Enum.AnimationPriority.Action
        reloadtrack.Looped = false
        reloadtrack:Play()
    else
        return
    end
end)
tool.Unequipped:Connect(function()
    if track then
        track:Stop()
    end
end)
