It worked fine for me. :+1:

I did notice that the search is case-sensitive, so if you enter "dave" it will not find anything.

But it finds "Dave" and displays the information.

That worked I didn't pay close enough attention to what he was doing in the video. Say I wanted to be able to enter the student's name in any case, I tried 

search = prompt.toLowerCase('Enter a students name [Jody], or type "quit" to exit');

But this didn't work, any suggestions?

You need to apply the conversion function after the prompt function, like this:

search = prompt('Enter a students name [Jody], or type "quit" to exit').toLowerCase();

And that's just half of process, you need to convert the name to lower case also so it will match:

  if (student.name.toLowerCase() === search) {

I made those changes and it works no if I type it in lowercase like this 'jody', but now it doesn't work when I enter it like I had to before 'Jody', very strange because I thought the whole point to .toLowerCase() was to be able to type in any case and have the information still math up.

Nevermind I went back and check my code, that worked I just hadn't made all the changes.
