Can someone fix this animation GUI button?

When a player clicks on the button, the animation I made is supposed to play but for some reason it won't...

local AIDs = {"849f4a5c72c46973ce179eed6c1a33f0"}
local Character = script.Parent.Parent.Parent.Character
local inuse = false
local b = script.Parent.TextButton
b.MouseButton1Down:connect(function(click)

    script.ExportAnim.AnimationId = AIDs[1]
    if not inuse then
        inuse = true
        Character.Animate.Disabled = true
        HoldAniTrack = Character:WaitForChild('Humanoid'):LoadAnimation(script.ExportAnim)
        HoldAniTrack:Play()
        wait(5)
        Character.Animate.Disabled = false
        inuse = false
    end
end)

I made the animation using Animation Plugin by ROBLOX anim link: http://www.roblox.com/dancetype2-item?id=171981401
