The "updated" message sounds suspiciously like ID thinks there was already a TOC someplace. Did you have a text cursor active in your document someplace? If so, there's a good chance ID repalce that story with the TOC.
When you create a TOC there should be nothing active, and you must always place the TOC stroy as its own story, not threaded with anything else.
ye that or the TOC frame is off the page and you have preview on or you created a tiny TOC text frame by accident.
What do you see on the page? A empty frame? Just a title?
You gonna see the paragraph style that you created.
See "keep options", the option keep with the next must be 0 (zero), the option Start paragraph must be "anywhere"
I hope it helpful.
Thanks for the tips. Nothing worked, although I suspect there was a hidden Text box somewhere that contained the ToC that I still can not find. Eventually I saved it as a new ToC style, named it and it gave me the loaded cursor and allowed me to place the Toc on the desired page. So, that was my work-around. Thank you for your suggestions.
