Thanks so much!
One thing I have learned today is CR3 can't read links with spaces in it. I've also notice you can't select the link at the top of the page. It highlights the second down on any page of links.
I've been using BD to insert a TOC at the beginning of the html as work around for the missing TOC
While I can fix link space issue the other makes it hard to navigate when that is the chapter you want to go to.
