Unable to cast Array to float? (Solved)

Making an animation for a button, and I come across this error. Here's the code:

local player = game.Players.LocalPlayer.Character
local animation = game.ReplicatedStorage.Kamehame
local track = player.Humanoid:LoadAnimation(animation)

function onClick(mouse)
    track:Play{}



end

script.Parent.MouseButton1Down:connect(onClick)

This is a LocalScript. Any answers?
