There are two completely seperate issues here, the deletion of your answer and the closing of your question.
Why was my answer deleted?
This is the easy one. It doesn't actually answer the question, given the requirements of an answer on this site. Your answer is almost entirely an external link. When writing an answer you should write it such that the reader doesn't need to follow any links. It's great if they want to, but your answer should answer the question with every single link in the answer removed. There are several reasons for this, discussed in several places on meta. Some of the high points:
- Link rot; what happens when the target site shuts down?
- How do users know if they can trust links?
- It's rude. We're looking to be a place where people can find answers, not places where the go to be linked to places that link to places that link to places that happen to be slightly related but don't actually answer the question, or if they do, require way more work for the reader than they should.
If you have an external resource that you feel answers the question you should quote/summarize enough of the resource (citing as appropriate) so that your post answers the question without needing to follow the link.
Why was the question closed?
Because it's unclear what the person is asking for. Even you didn't know. You found something that you think might be related, or at least might be something that the OP can use to figure out the answer, but as it is, with the information in the question, those 5 users felt that it was impossible to answer the question. If the OP is able to clarify their post (hopefully helped by people asking clarifying questions to direct them to the unclear points) the question should become clear enough to be reopened.
