Is my code incorrect

Hey there, Having a bit of a struggle with this one. I thoroughly watched the videos and must have missed this concept. Can someone help me get it right and explain what's happening in the right code? Thanks!

musical_groups = [
    ["Ad Rock", "MCA", "Mike D."],
    ["John Lennon", "Paul McCartney", "Ringo Starr", "George Harrison"],
    ["Salt", "Peppa", "Spinderella"],
    ["Rivers Cuomo", "Patrick Wilson", "Brian Bell", "Scott Shriner"],
    ["Chuck D.", "Flavor Flav", "Professor Griff", "Khari Winn", "DJ Lord"],
    ["Axl Rose", "Slash", "Duff McKagan", "Steven Adler"],
    ["Run", "DMC", "Jam Master Jay"],
# Your code here
for members in musical_groups:
    print( " ,".join(members))

Hi Jorge Morales,

You’ve placed your comma in the wrong place. It should be ”, “. So adjust your string so that it follows the pattern comma-space, instead of space-comma.
