Some of the key things to notice are:
1. At the beginning you have the PreSaveAction function. This function is called every time someone clicks on the finish button. It is executed before anything is saved. If it returns true it saves the data, if it returns false it returns you to the survey(leaving all of your input) and nothing is saved.
2. The getTagFromIdentifierAndTitle function was found on the SharePoint Designer blog and is better described there: http://blogs.msdn.com/sharepointdesigner/archive/2007/06/13/using-javascript-to-manipulate-a-list-form-field.aspx. Basically it goes and gets the value of what is stored in the input fields. I found a modified version as the original didn't include radio buttons which were what I primarily used in my survey. It can be found here: http://sharepointmalaya.blogspot.com/2009/04/trigger-javascript-events-when-choice.html.
3. It also was important to pass the correct title to the getTagFromIdentifierAndTitle function. I found the titles by viewing the source of the page. It was found in a cooment that looks like this: Fieldname="Name of Field". It appeared right before the definition of each radio button. You then pass that name in as the title.
4. The rest of the code is mostly specific to the survey I created. It goes through and finds each of the input fields and then checks to see if they are correct. If any one of the answers is incorrect it sends them a message and returns them to the quiz. If they are all correct then it saves the quiz.
Well it was a fun adventure in JavaScript and I learned a few things. I am sure the code cloud probably be a little more efficient but it got the job done.
