Can someone please help? Cross-references have stopped working in Word 2007

[WaltR]

Something has gotten screwed up somewhere. I can't create cross-references to bookmarks, either from References tab or Insert tab. When I open the Cross-reference dialog, everything looks good, bookmarks are all listed, but when I click Insert, nothing happens.



The last document I worked on I created a cross-reference and it work okay, then I started playing around with the Hyperlink style and I think I messed something up.

Is there a way to undo everything I did to the Hyperlink style without nuking the Normal.dotm template? If not, and I do torch the Normal template, what will become of all the documents I created with it? Will they still contain all the errors they previously had?

I need advice on how to get the cross-references working again with the least amount of damage.

Thanks.
