a) I can't seem to create any new options for finished basement, and simply get the following msg: image description

I have had this error for other parameters too and just assumed I was exceeding certain acceptable ranges, but I am getting it every time here. Do you know what's causing this?

b) Does the Constant ACH variable refer to the ACHn from in/exfiltration through the basement enclosure, or from mechanical ventilation, or both? Why is this value zero for all finished basement options, and 0.1 for unfinished basement options?

b) The constant ACH variable refers to the ACHn from in/exfiltration through the basement enclosure, not mechanical ventilation. It is zero for finished basements because their leakage is included in the whole house ACH50 input.
