Is there a resource that will explain what error codes mean and how to fix them?

For example, today I got the error code: ‘snowman’ is defined but not called in your program

That doesn’t mean anything to me and it certainly won’t help my students. Is there a resource where I can look up these error codes meaning/description and how to fix them?

Can you link the project so we can better help you? It sounds like a variable or function named snowman was created but not used.

Thanks. I figured that out. What I’m looking for is a link to a resource with common error codes with explanations as to what they mean and ways to fix them. Thanks
