To create subparagraph numbering in Microsoft Word, follow these steps:

1. Select the paragraph(s) you want to apply the subparagraph numbering to.
2. Go to the Home tab and click on the Multilevel List button in the Paragraph group.
3. Choose the option "Define New Multilevel List" at the bottom of the list.
4. In the dialog box that appears, you can customize the numbering format for each level. For example, for Level 1, you can choose "1, 2, 3..." and for Level 2, you can choose "1.1, 1.2, 1.3...".
5. Make sure to check the box "Legal style numbering" to ensure that the numbering updates correctly if the main paragraph number changes.
6. Click OK to apply the multilevel list to your selected paragraphs.

Now, when you press Tab after a main paragraph, it should automatically create a subparagraph with the correct numbering format. If you change the main paragraph number, the subparagraph numbering should update accordingly.
