Andrew,

Awesome! The GetCrossReferencedItems/wdRefTypeHeading is the key! I need to read up on that a bit more. This might solve another problem for me too!

Had to make two minor tweeks to your example code:

If InStr(Trim(v), Trim(strTargetHeading)) = 1 Then

added the Trim() and set the find location to one. The first test case I ran using "3.1" found "2.3.1".

Thanks for the help!
