Tom Hollingsworth wrote another must-read blog post in which he explained what one should do before asking for help:
If someone comes to me and says, “I tried this and it failed and I got this message. I looked it up and the response didn’t make sense. Can you tell me why that is?” I rejoice. That person has done the legwork and narrowed the question down to the key piece they need to know.
In other words (again his), do your homework first and then ask relevant questions.
