Hey Brian, here is what you should have so far.

      var myArray = ["sugar", "rush", "fix", "it", 3.14, 42];
      var thirdElementInArray = myArray[2];
      myArray[30] = "treehouse";

Tip: 31 is actually 30 since 0 is counted as well. +1 on Jason's explanation for why var is not needed.

Hi Brian,

The myArray variable has already been declared and so you don't need to use the var keyword again.

myArray[30] = 'treehouse';
