How do I make an animation play on a tool with music?

I want to try working on my own emote game for recording purposes, and I can't figure out how to attach animations to a tool. The scripts I've been using don't work, and everything else I've looked at is outdated. This is the only thing I've found:

enabled = false;
local l__Parent__1 = script.Parent;
local u1 = nil;
local l__BGM__2 = workspace:WaitForChild("BGM");
local l__SongLoop__3 = l__Parent__1:WaitForChild("dancepart").SongLoop;
local l__LocalPlayer__4 = game.Players.LocalPlayer;
function onActivated()
    if enabled == false then

    else
        u1:Stop();
        u1:remove();
        l__SongLoop__3:Stop();
        l__SongLoop__3.Parent = l__Parent__1.dancepart;
        enabled = false;
        l__LocalPlayer__4.Character.Humanoid.WalkSpeed = speed;
        l__BGM__2.Volume = 1.7;
        return;
    end;
    local l__Torso__2 = l__Parent__1.Parent:FindFirstChild("Torso");
    u1 = l__Parent__1.Parent:FindFirstChild("Humanoid"):LoadAnimation(l__Parent__1.dance);
    l__BGM__2.Volume = 0;
    l__Parent__1.DanceObject.Value = u1;
    u1:Play();
    l__Parent__1.dancepart.SongLoop:Play();
    l__SongLoop__3.Parent = workspace;
    enabled = true;
    speed = l__LocalPlayer__4.Character.Humanoid.WalkSpeed;
    l__LocalPlayer__4.Character.Humanoid.WalkSpeed = 16;
end;
function onUnequipped()
    u1:Stop();
    u1:remove();
    l__SongLoop__3:Stop();
    l__SongLoop__3.Parent = l__Parent__1.dancepart;
    enabled = false;
    l__LocalPlayer__4.Character.Humanoid.WalkSpeed = speed;
    l__BGM__2.Volume = 1.7;
end;
l__Parent__1.Activated:connect(onActivated);
l__Parent__1.Unequipped:connect(onUnequipped);
l__LocalPlayer__4.Character:WaitForChild("Humanoid").Died:Connect(function()
    l__SongLoop__3:Stop();
end);

This doesn't work from my testing, if anybody is able to help it'd be greatly appreciated!
