Psychrometric Chart Operate Wrong

  1. Solution exception:Local variable ‘exWork’ referenced before assignment.

When i turn _runit to true, i met with this error. But i cant find where was wrong, even cant find ‘exWork’ parameter. Do anyone know how to do? Thanks in advance.

That’s not how you are supposed to use the Clothing component. You should connect it to a native Grasshopper “Mass Addition” component before plugging it into the psychrometric chart.

If you still have this issue after that, please post a sample file that recreates the error.
