A family of Microsoft word processing software products for creating web, email, and print documents.
Are you using the "Advance value (skip numbers)" option in the Set Numbering Value dialog box?
In that case, you have to hide hidden text. At File > Options > Display, ensure that "Hidden text" is cleared.
However, in almost all cases, when you want to customize your numbering, there is a better approach than to use the "Advance value..." setting.
As Charles proposed, feel free to post back with a sample document.
