What was wrong with the code snippet I posted on your other thread (which seems to involve the same data as this one)?

Have you really tried running any code on your own? What have you tried? If you did try the snippet I provided earlier, and had trouble with it, why didn't you post a reply there? Be explicit and clear about what you tried: the actual script, the actual input data, the actual output data, how that actually fell short of your intentions.

Please give some relevant feedback to the suggestions you've been given, so we can help you move forward.
