General Umberto NXT CO2 / Parrot Tutorial
« on: January 31, 2011, 10:15 »
I now finished the second tutorial task to calculate a network for the production, use and disposal of a parrot. But there is a problem when I try to calculate the flows. The first input is not ready to calculate (grey arrows) and so the rest of it\'s influences can also not be calculated. I did all the things that are named in the tutorial but he can\'t calculate that. Can you help me?

Thanks in advance and

Best regards,

Martin Hellmann
