I can insert the cross-reference using Special - Cross-Reference and "Source Type: Paragraph" but then when I click on "insert," the Source Type changes to "Cross-Reference Markers" which I don't want to use. Why is it changing? This happens randomly, and I haven't figured out any way to use only Paragraphs as the source type for cross-references.
Be aware that whether you use ST:Paragraph, or ST:Marker, the created data structures in the document are the same. You can confirm this by examining the MIF. The real difference between them is that By-Para creates a new Marker, and By-Marker requires a pre-existing Marker. Once created, FM has no idea which method was used.
So this would seem to be a problem with the Xref pod. Anyone who can help with that is going to want to know what FM version and patch level you're on.
Version, patch and a screen shot of the X-ref dialog box as you are ready to click Insert would be ideal.
I think I figured out my issue. My document was started by using an older version that had been previously used in a book, and the heading already had a marker for a table of contents. I recreated a new heading, without the marker, and then when I inserted the cross-reference, it stayed as a "Paragraph" and did not revert to the "Cross-reference marker."
Thanks - the "pre-existing" marker was my clue.
