I'm not sure why my code isn't working. I get to the last step and it tells me that Task 1 is no longer passing.

I didn't change any part of task 1 but when I try to join sundaes it gives me that error.

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

Hi Ethan, if you ever encounter a task is no longer working issue, it generally means something is preventing your code from running properly.. such as a syntax issue.

display_menu = sundaes.join(", ")

You are not able to call the join method on a list because lists don't have a join method.

display_menu = ". ".join(sundaes)

That is what you are looking for.

You also have to re assign the result to menu too.

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)
