Basic JavaScript: Using Objects for Lookups, Pls Help

Tell us what’s happening:
I got this error message:

phoneticLookup("") should equal undefined

Your code so far

// Setup
function phoneticLookup(val) {
var result = "";

// Only change code below this line
var lookup = {
  "alpha": "Adams",
  "bravo": "Boston",
  "charlie": "Chicago",
  "delta": "Denver",
  "echo": "Easy",
   "foxtrot": "Frank",
result += lookup[val];
// Only change code above this line
return result;

Oops!!! Sorry, my bad. Post edited!!!

Well, pay attention to what is happening on this line:

result += lookup[val];

Hint: It is a very simple fix;
