This is in the back of the flowsheet. When I enter a new stream with its flow, composition, temp and pressure the MW is not calculated and the
unit op can't be calculated either. It tells me incomplete stream specification. I think it is a small error but I haven't found it.

Re: incomplete stream specification
For feed stream, please specify all compositions and total flow rate or compound flow rates (you can set them explicitly to zero) and pressure and temperature. Once the stream flashes, you can change the pressure and or temperature specification by clicking on one of the black properties (e.g. overall enthalpy, vapor phase fraction) and re-flash the stream at the new specification.
In your flow sheet, some of the feed compositions remain unspecified. In stream 27(1), these are ethane / propane / butane. In stream 29, most are unspecified. You can right-click one of them and choose "Remaining composition", this will zero out all others.
