Why is my userinput not doing anything when i click the button "E"? [Ansvered]

code:

wait(3)
local hitbox = workspace:WaitForChild("UnderGround_Area").HitBox_Enter_Sewer
local input = game:GetService("UserInputService")
local plrname = game.Players.LocalPlayer.Name
local plr = game.Players:WaitForChild(plrname)
local UI = plr.PlayerGui:WaitForChild("Sewer")
local run = false
--
input.InputBegan:Connect(function(input)
    if input.KeyCode == Enum.KeyCode.E then
        print("Pressed E")
    wait(1)
    end
    end)
