You know, the people that help out here are all un-paid volunteers, so please HELP US HELP YOU. Providing the DDL scripts (CREATE TABLE, CREATE INDEX, etc.) for the tables affected, and INSERT statements to put some test data into those tables that shows your problem will go a long way in getting people to look at your issue and help you out. Please include code for what you have already tried. Don't forget to include what your expected results should be, based on the sample data provided. As a bonus to you, you will get tested code back. For more details on how to get all of this into your post, please look at the first link in my signature.

If you can't explain to another person how the code that you're copying from the internet works, then DON'T USE IT on a production system! After all, you will be the one supporting it!

Never stop learning, even if it hurts. Ego bruises are practically mandatory as you learn unless you've never risked enough to make a mistake.

Can you please show what you've tried that hasn't worked. We're more than willing to help. But, we're not doing your homework for you.
