@ejazbee, You are trying to use symbols which have no simulation model associated with them. Please read the Simulation Tutorial: [https://docs.easyeda.com/en/Simulation/Headings/index.html](https://docs.easyeda.com/en/Simulation/Headings/index.html)

@ejazbee, Please note that there are currently some problems with some of the simulations in the Tutorial. Workarounds are described here: [https://easyeda.com/forum/topic/tutorial-examples-ammeter-seems-to-be-an-open-circuit-750da3761f664dc0987be6084f60eada](https://easyeda.com/forum/topic/tutorial-examples-ammeter-seems-to-be-an-open-circuit-750da3761f664dc0987be6084f60eada)
