Sure, I can definitely help you with that!

To set up nested numbered headings in Word, you can follow these steps:

1. First, make sure that you have your headings formatted as "Heading 1" and "Heading 2" styles. You can do this by selecting the text you want to format as a heading, and then choosing the appropriate style from the "Styles" section of the Home tab.
   
2. Once you have your headings formatted correctly, place your cursor where you want to insert the nested heading (for example, after "1.1" if you want to add "1.2").
   
3. From the "Home" tab, click on the "Multilevel List" button in the "Paragraph" section. This will open a dropdown menu with several different list styles.
   
4. Choose the list style that you want to use for your nested headings. The default style should work fine for most cases, but you can also choose "Define New Multilevel List" to customize the numbering and formatting.
   
5. Once you have selected your list style, you should see the next number in the sequence appear after your cursor. Type in the text for your nested heading, and then press "Enter" to create a new line.
   
6. If you want to create a subheading under your nested heading (for example, "1.2.1"), simply place your cursor at the beginning of the new line and press the "Tab" key. This will indent the text and create a new level in the list.
   
7. Continue typing in your subheading text, and then press "Enter" to create a new line. If you want to create another subheading at the same level, simply press "Tab" again to indent the text further.
   
8. Repeat these steps as needed to create all of your nested headings.

That's it! You should now have a document with nested numbered headings in Word. Let me know if you have any other questions or if there's anything else I can help you with.
