While building a CO2 Scubber in the garage it is stating that I do not have all the required materials. I can't get it to accept the small circuit board even though the availble list on the side states that I have a small circiut board, and it is not burned out. The only thing I can think of is that a CO2 Scubber can't be built in a garage but it is listed as something that can be built.
