Do you have any troubleshooting suggestions for my keyboard input script?

Hey there, today I've been messing with keyboard input (using the wiki page as my primary resource). In short, it's not registering input from the Q and E keys when testing as a published place or in the local test server. Works fine when running it with the Play (F5).

I've done some investigating with print()

_G.TileScriptSelected = 1

function onKeyPress(inputObject, gameProcessedEvent)

    if inputObject.KeyCode == Enum.KeyCode.Q then -- I assume this must be the issue...
        print("TEST.") -- ... since THIS print never gets run when Q is pressed
        if _G.TileScriptSelected > 1 then
            _G.TileScriptSelected = _G.TileScriptSelected - 1
            print("Q was pressed: ".._G.TileScriptSelected)
        end

    elseif inputObject.KeyCode == Enum.KeyCode.E then -- This never runs either when pressing E

        if _G.TileScriptSelected < 10 then
            _G.TileScriptSelected = _G.TileScriptSelected + 1
            print("E was pressed: ".._G.TileScriptSelected)
        end
    end
end

game:GetService("UserInputService").InputBegan:connect(onKeyPress)

I'm pretty stumped. Been at it for a few hours now. Tried it on an entirely fresh map in a localscript and it ran fine. I don't have any other keyboard input scripts that could interfere.

Perhaps I should try the other method on the page - ContextActionService. But I'd like some suggestions of things I could possibly try so I learn more from this.

Thanks a bunch!!!!
