Hi there,

The issue with the prompt seems to be on line 11 of student_report.js - the error is about closing parentheses, but it's actually the quotes in the string. Currently, there are single quotes around the string, but single quotes are also used inside the string. When it hits another single quote, it's going to think the string is ending, and the rest of the code there will just cause an error because it doesn't recognize it as the rest of the string. You can get around this by using an escape character "\" before each of the single quotes, or by using double quotes in the string. Your options are:

  • (or type \'quit\' to exit) - the escape character won't show up, it just tells it not to end the string here
  • (or type "quit" to exit)
  • leave the string as-is, but enclose the whole thing in double quotes instead

When you get something not loading, there's usually a syntax error somewhere. You can pull up the JavaScript console in the browser to help figure out what's going on - in Chrome it's ctrl-shift-j and in Firefox it's ctrl-shift-k. Hope this helps!

I believe I fixed the issue but the prompt window still does not show up. Could you please help me out another time? Thanks

Hi again,

On this one, it's not loading because there's a loop that isn't closed. Here's the snippet in question:

for (var i = 0; i < students.length; i++) {
  search = prompt("Please type a name to look up student directory. Type quit to exit");
  if (search.toLowerCase === 'quit') {
    break;
     //need a curly brace here
}

Right now, it's closing the 'if' block, but not the 'for' loop. If you add that curly brace, the prompt comes up again.
