Do you have the Dispay_Menu function? Did you mean to spell it as Display perhaps?

Yea, it's a little confusing. Basically you need to take the array of values you split the string into, join them back together as strings again (but with a comma and space instead of semi-colon) and use that new string as the placeholder text in the menu string using the format method.

available = "banana split;hot fudge;cherry;malted;black and white"

sundaes= available.split(";")

display_menu = ", ".join(sundaes)

menu = "Our available flavors are: {}.".format(display_menu)

You got the gist of it!

In the 3rd task, it's asking you to use the .join() function. You've already used the .split() function successfully.

Here's how I solved the problem.

available = "banana split;hot fudge;cherry;malted;black and white"
sundaes = available.split(';')

# display_menu joins the list into separate strings. 
display_menu = ", ".join(sundaes)

# this takes our newly formatted strings and formats it into the string.
menu = "Our available flavors are: {}.".format(display_menu)

Before you solve this task with my example, I highly recommend you to play around in your console so you fully understand .split() and .join(), since you'll be using them a lot in later tasks.

I hope this helps!
