It's difficult to read the unformatted code, but one thing caught my attention. In the function getstudent you have this line:

  var result += '<h2>Student: ' + student.name + '</h2>';

You probably meant to write "=" instead of "+=" here, since you cannot add to a variable that is just being created.
The other code should function once that error is corrected.

In future, to facilitate a complete and accurate answer, always format your code (see the Markdown Cheatsheet) and include a link to the course page you are working with.
