So many questions here. So let's start from the basics.
Did you create a TOC? Note that while RoboHelp does offer an ability to automatically create one for you, it is up to you as the help author to tell RoboHelp to create the TOC.
Assuming you have created a TOC and are still having issues, are you using Conditional Build Tags to exclude information? If so, that may explain things.
Can you share a screen capture of what your TOC looks like in the editor and what your output looks like?
Thanks Rick. You're right there are a number of questions here. I did create a TOC and then included that as part of the layout. That helped. However, when I use the "Show" and "Hide" buttons. After I "Hide" the TOC and go back to view it, It disappears from the Contents.
Thanks for your input.
