why is answer b incorrect in question 5 of 5 in the section /variables/scope#

answer b the 5th question for the lesson /variables/scope# seems to be "treehouse", it appears to be within the scope of function bam; var part 2 "treehouse". console.log(part2) appears to call the value "treehouse".

Hi Eddie,

The order of the questions change every time you do the quiz. Could you post the full question please?

I assume this is the question you are talking about?

var part1 = "Team ";

function bam() {
    var part2 = "Treehouse";
}

bam();

console.log(part2);

The answer is Reference Error : Part 2 is not defined. The variable part 2 is only available in the scope of function bam. The part2 variable is not global so when you try to print you get the value of undefined(since part2 is local to the function).

Hope that helps.
