UserInputServer Not working correctly?

For some reason my UserInputService is working. I have it set up to where if a certain key was pressed, E, an animation would be loaded into the character and the animation would play. After a few failed attempts, I tried a print function, but turns out that doesn't work either. The entire thing doesn't even run when the button is pressed.

The code is simple, just a few lines, which is in a LocalScript which is in the StarterPlayerScript. I have also tested it in StarterGui but that didn't work either.

`local uis = game:GetService("UserInputService")

local player = game.Players.LocalPlayer

local char = player.Character

uis.InputBegan:Connect(function(input)

if input == Enum.KeyCode.E then

local smash = Instance.new("Animation")

smash.AnimationId = 'rbxassetid://2941877623'

local usos = char.Humanoid:LoadAnimation(smash)

usos:Play()

end

end)`
