Before asking a question, first make an effort to find the answer to your question. A lot of questions have been asked and answered before, so please spend some time trying to solve the problem on your own (e.g., search the web, search these web pages, etc.), and show us that you did so when you ask your question.
When asking, (1) be details, and (2) demonstrate that you have made an effort, e.g., "I am having trouble frobbing the foo. I searched the web and only found information regarding how to frob a bar, but that seems unrelated." Provide as many relevant details as possible reproducing them as exactly as possible.
