This starter contains three button sprites — Add Item, Clear List, and Delete Item — with their button costumes already loaded, and a global shopping list variable. The buttons don't do anything yet: writing their scripts is your job.

Make sure shopping list starts out as an empty list, then give each button a when I am clicked script: Add Item should ask the user for a new item and add their answer to the list, Clear List should check that the user is sure and then set the list back to empty, and Delete Item should ask which numbered item to remove and delete it. Test each button as you go.

Your work autosaves (and you can use the Save button); earlier versions are available from the Revisions dropdown.
