Why can't Character be found in LocalPlayer when in game?(It will work in normal studio test)

Hello! I am currently working on an interactive test and everything works great! However, I realized I never tested it in actual game mode. And for some reason I get this in the server output:

Players.Player1.PlayerGui.MidnaGui.Frame.ImageButton.LocalScript:2: attempt to index field 'Character' (a nil value) 15:04:41.272 - Stack Begin 15:04:41.272 - Script 'Players.Player1.PlayerGui.MidnaGui.Frame.ImageButton.LocalScript', Line 2 15:04:41.273 - Stack End

I have the script in the Player's PlayerGui>MidnaGui>Frame>ImageButton>LocalScript

Mid = game.ServerStorage:FindFirstChild("Midna Anim")
prt = game.Players.LocalPlayer.Character:WaitForChild("Par2")--This is where it supposedly can't find Character within Local Player
num = game.ServerStorage.NumValue
gui = script.Parent.Parent.Parent
txt = gui.Frame2.TextBox
plr = game.Players.LocalPlayer
txt.Text = "What is it, " ..plr.Name .."?"

script.Parent.MouseButton1Click:connect(function()
    if num.Value == 1 then
    prt.Parent.Head.Apear:Play()
    Mid.Parent = game.Workspace
    Mid:MoveTo(prt.Position)
    gui.Frame2.Visible = true
    num.Value = 2
    elseif num.Value == 2 then
        if prt.Parent.Head.Apear.isPlaying == true then
        prt.Parent.Head.Apear:Stop()
        end 
    prt.Parent.Head.Vanish:Play()   
    Mid.Parent = game.ServerStorage
    gui.Frame2.Visible = false
    num.Value = 1
    end

end)

I'm not sure why it can't find the character in game but can in studio. Any help?

Thanks! ~Minikitkat
