Possible bug found in JavaScript course challenge?

I believe I found a bug in a JavaScript course challenge. I submitted an a bug report via email, but got a message back from support saying it's not broken. However, it is still not letting me move forward. Here is the link:

https://teamtreehouse.com/library/javascript-loops-arrays-and-objects/tracking-multiple-items-with-arrays/using-array-indices

Here is the challenge: Challenge Task 2 of 2 Now, use console.log() to log out the last item in the array.

Code:

var players = ['Jim', 'Shawna', 'Andrew', 'Lora', 'Aimee', 'Nick']; console.log(players[5]);

Bummer Message: Bummer: Use [ ] and a number to access an item in an array: players[0]

Hi there, Scott Vojik ! Support is correct. This is not a bug. These challenges are cumulative. Each successive task should contain the code that was present in the step before it. Step one asks you to log out the first name and step 2 asks you to log out the fifth name. This means there should be not one, but two console.log() statements. Take a look at this informational tip in the area where the "Bummer!" would appear. This is visible before you hit "Check work":

Important: In each task of this code challenge, the code you write should be added to the code from the previous task.

Hope this helps! :sparkles:

Ahhh ok, got it. That makes sense. That little important message would be a good thing to display on the second challenge screen!

Scott Vojik it is on every challenge screen before you hit "Check work". But once you hit that, it will be replaced with a Well done! or a Bummer! message :smiley:
