Hello! Here is a corrected version of your code. Notice how the list items are going correctly from 1 to 6, instead of repeating 2 over and over. When you have an ordered list (ol), you need the list item elements (li) to be adjacent or it won't count up correctly. Since each "inner" unordered list is itself a list item of the ordered list, they belong inside the list items of the larger ordered list.
Here is a link to the corrected code.
