newAnim a nil value even though its a global variable?

Now i know why this doesen't work and it says newAnim is a nil value even though its a global variable?

local p = game.Players.LocalPlayer
local anim = script.Animation
local serv = game:GetService("UserInputService")
local keyCodeQ = Enum.KeyCode.Q
local keyCodeE = Enum.KeyCode.E
local char = p.Character -- their character
if not p.Character then -- checks to see if the character exists
    repeat wait() until p.Character -- if not, it waits until it exists
end
local human = char:WaitForChild("Humanoid") -- the character's humanoid (required to load an animation)

serv.InputBegan:connect(function(key,processed)
     if serv:IsKeyDown(keyCodeQ) and serv:IsKeyDown(keyCodeE) then -- change 'F' to your key, also checks to see if a player is typing (etc.) or not
        print("Starting animation!")
         newAnim = human:LoadAnimation(anim)
        newAnim:Play()
    end
end)


serv.InputEnded:connect(function(input)
    if not serv:IsKeyDown(keyCodeQ) and not serv:IsKeyDown(keyCodeE) then
        newAnim:Stop()
    end
end)
