Hi there. I've got trouble with simulating in my circuit. After "simulate" button pressed, the program says "error building graph" and nothing happends. Help me, please.

The error was in source name. Previous source on the page was "V1", which was deleted. After rename current source "V2" to "V1" the error disappeared. But now it says "Type error: b is not a function".

Hi @belegnar,

Can you provide a link to a public circuit that is causing this error for you. I would be happy to take a look and help you fix it.

Thank you very much

Hi @belegnar, I see two problems which both need to be solved to get your circuit to simulate. First, in the version I'm seeing at this moment, both your DC voltage source and your sine signal source are named "V1" -- change one of them to be "V2" or similar so they don't conflict. Second, your NPN BJTs are named "VT1.1" and "VT1.2", but the period character "." is not allowed in element names. If you change these to be, for example, "VT1a" and "VT1b", you'll find that you're able to simulate.

I agree that our error messages in these cases are not too helpful right now, and we will look into improving that!

It works! Thank you. This site is great job!
