How do I make player do a default dance?

I am trying to make the local player do a default dance, and it worked (mostly) , but either sometimes it wouldn't work, or it would only work for a couple seconds, so I added a loop, but that does not work either, because it is too fast of a loop and I do not know the exact time to do. Can anybody help me with this, I've already looked for this type of stuff but there is nothing to answer my question.

Server Script:

replicatedStorage = game:GetService("ReplicatedStorage")
replicatedStorage.RE.Dance3.dance3:FireClient(plr,true)

LocalScript:

function dance3(operation)
    if operation == true then
        local name = game.Players.LocalPlayer.Name
        local Humanoid = game.Workspace:WaitForChild(name).Humanoid
        local animation = Instance.new("Animation")
        animation.AnimationId = "http://www.roblox.com/asset/?id=182436935"
        game.ReplicatedStorage.RE.Dance3.Value.Value = true
        local animTrack = Humanoid:LoadAnimation(animation)
        while game.ReplicatedStorage.RE.Dance3.Value.Value == true do
            wait()
            animTrack:Play()
        end
    elseif operation == false then
        game.ReplicatedStorage.RE.Dance3.Value.Value = false
    end
end
game.ReplicatedStorage.RE.Dance3.dance3.OnClientEvent:Connect(dance3)
