When trying to submit a question, I'm receiving the following message:
Your post does not have much context to explain the code sections; please explain your scenario more clearly.
Where should I write my context and how?
You get that message when you're trying to post just a bunch of code without any explanation of what you're trying to accomplish, what problems you're running into, what approaches you have already tried, etc.
If you want people to help you, you have to be clear about such things. Try to post as little code as possible while still posting enough to clarify the issue, and also describe your problem clearly. A huge block of code with an additional "This doesn't work" makes it extremely hard for people to be of any assistance.
Bottom line: You should help people to help you, as much as you can.
