Issues with UserInputService not detecting keys?

I've tried to make this chat GUI, with a custom chat bar. As usual, the script works in Studio, but not in the client, and I was wondering if I would need to change it otherwise.

The script

local service = game:GetService("UserInputService")
local gui = script.Parent

service.InputBegan:connect(function(keyPressed,gameProcessedEvent)
    if gameProcessedEvent then 
        return  end
    if script.Parent.Parent.Status.Value == true then
        if keyPressed.KeyCode == Enum.KeyCode.E then
               gui.TextBox:CaptureFocus()
        end
    end
end)
