Roja kajoka Wow! You are so close here. I only have to change one variable name and this whole thing works beautifully. The problem is in your join statement. You are attempting to join musical_groups, but that is the outer array. You should be joining group, which is the inner array.

You wrote:

group = ", ".join(musical_groups)

But that should be:

group = ", ".join(group)

Hope this helps! :sparkles:
