Please see How do I post a question effectively?: The best and usually fastest way to get an answer is to post as much of the following as possible: code that complies, a description of what the code is supposed to do (and possibly a description of what it's currently doing instead), a small but representative sample of the input data, the expected output for that input data, the current (presumably incorrect) output, and any error messages you're getting (copy/pasted exactly).
