Hi Netta,
Step by step instructions for setting up your numbering can be found here:

(Mac version:http://www.brandwares.com/bestpractices/2016/06...)
This method may seem a bit of work but not using it for important work is asking for trouble. Once you have it set, you can save a template with it and use that template for new documents where you need good numbering that can survive editing.
This forum is a user-to-user support forum. I am a fellow user.
An example of using style-based numbering for questions of this type can be found on my downloads page:

With the cross-referencing, it depends on how your numbering is set up. Using list numbering will not do it. Again, refer to Shauna's page.
If you want, save a sample document with the problem on OneDrive or Dropbox and paste a link here. Remove any confidential or sensitive information first. I or someone else can take a look at it.
For OneDrive: See https://support.office.com/article/share-onedri...
For DropBox: See https://help.dropbox.com/files-folders/share/vi...
I hope this information helps.
Please let me know if you have any more questions or require further help.
