Referencing this node, this node, and this node, it looks as though you received some very good feedback, but have provided very little regarding any further attempts.

What does your code look like now, and what specific problems are you experiencing? What have you learned thus far? Given the quality replies you have been given, combined with the minimal feedback on your part, I'm afraid you're going to find that this 4th thread receives very little attention.

Perhaps you should spend a little time focusing on the resources given in the prior responses. Once you've digested that, the "direness" of your request should diminish considerably.

Update: Made links more site-friendly and added a little whomp-ass.
