How do I fix invalid argument error?

Help and Feedback Scripting Support
#1

My script works fine as it is, but I keep getting this error:
ServerScriptService.RoundController:39: invalid argument #2 to ‘random’ (interval is empty)

This error corresponds with my player chosen variable. My full script is shown here:

for _,seat in ipairs(workspace.TableArea.Chairs.Seats:GetChildren()) do
		if seat:IsA("Seat") and not seat.Occupant then -- if the seat is a seat and doesn't have anyone on it
			local playerchosen = math.random(1,#players)
			local chosenchar = workspace:FindFirstChild(players[playerchosen])
			seat:Sit(chosenchar.Humanoid)
			table.remove(players,playerchosen)
		end
	end

Does anyone know why this is happening and/or how to fix it?

#2

This happens when the first argument is greater than the second, so there likely aren’t any players.
