Currently can solve a set of equations with the solve block. This works now only because I manualy copy the summation outcome(grey area) in the solve block (green area) and set it equal to zero. If I just enter the summation of forces/moments and set it equal to zero I won't get any result presented(red highlighted). SO what goes wrong/what should I do to not have to copy the outcome every time manualy in the solve block.
