So? It is almost certainly doing what you told it to do.  Since you didn't post your code (you might need to post the entire Project -- to do that, compress the folder containing the Project files and attach the resulting .zip file), we can't provide much help.

If you do provide your code, tell us what you would like the code to do, in case it isn't obvious.
