Hi michael. The thing is you are using the syntax for join wrongly. It is not the same way as split. In join if you want to join a list seperated by a comma then you will have to write ans=",".join(input). And another problem with you're code is that they have asked you to reassign menu and not available. Try it on your own. I have also added my code below for you're reference. 

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(';')
menu = 'Our available flavors are: {}.'
display_menu=", ".join(sundaes)
menu=menu.format(display_menu)

If you want to go the "really brave" route and accomplish the goal all on the same line where menu is currently set, you can do this: 

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(";")
menu = "Our available flavors are: {}.".format(", ".join(sundaes))
display_menu = menu
