Would it be possible to upload the solution or an example similar to the lab about the tournament before the midterm on Wednesday? 

I didn't get very far after displaying the teams and iterating through the first round. I also didn't understand the parameter map part and couldn't figure out how to display different sets of teams after you click "Next". I understand the MVC part with the JSP but I need help with getting the right parameters and letting the server know to move on.

l would appreciate some visual help so I can be prepared for the midterm.
