How do I make a Animation play on a character when a Gui clicked?

I asked this on the forum and there was no response. Please help.

Just to give you a basic understand....

local Anim = Humanoid:LoadAnimation(Id)

Button.MouseButton1Click:connect(function()
Humanoid:PlayAnimation(Anim)
end)

Now all you need to do is fill in the blanks. :)
