Your project is private so only you can see it. Therefore the following is a guess. You have used one or more symbols (Pots and LM358?) in the schematic that are not from the EELib in Sim mode or from the Spice Symbols library and therefore they have no spice model associated with them. To resolve this, please read the Simulation Tutorial: [https://docs.easyeda.com/en/Simulation/Headings/index.html](https://docs.easyeda.com/en/Simulation/Headings/index.html)

Thank you, I've started reading it already.
