UserInputService does not detect input?

I've made a script that detects when a specific key is pressed. I have tried putting a print function to see if it was detected or not and it did not print the message. Could it be something to do with studio?

Script:

local uis = game:GetService("UserInputService")
local plr = game.Players.LocalPlayer
local chatting = false
local frame = script.Parent

plr.Chatted:connect(function(msg)
	chatting = false
end)

uis.InputBegan:connect(function(input)
	if input == Enum.KeyCode.Slash and game.StarterGui:GetCoreGuiEnabled("Chat") then
		chatting = true
	elseif input == Enum.KeyCode.Return then
		chatting = false
	end
	
	if chatting == false then		
		if input == Enum.KeyCode.Equals then 
		frame.Visible = not frame.Visible
		end
	end
end)

I am using a localscript btw

You have a little mistake out there on line 11:

 if input == Enum.KeyCode.Slash -- no

if input.KeyCode == Enum.KeyCode.Slash -- yes

you forgot to put keycode there, now it should work..
