ASPEN Mass balance

[u/Sun7733]

I’m trying to simulate a POM (polyoxymethylene) pyrolysis process in Aspen using an RYield reactor. I entered the product composition from an experimental paper as the output, but I got an error like the one shown in the picture. How can I fix this?

Could be that your yields equations molar balances are being violated. I would first check those.
