File names appear in WebHelp Content list in FrameMaker 12

Regarding the file names, I had this issue previously and solved it; I hope I remember the solution correctly.

Next to the Settings file, click the Edit button.

In the Publish Settings dialog box that opens, click Style Mapping.

Scroll down till you get to General Settings

Click General Settings.

You need to play with the settings here till you get what you want

1. Check Add all Topics to Table of Contents

2. Click on the drop-down box next to Topic Name Pattern.

instead of <filename>

you should  be able to select <$paratext>

This was for version 13.

I hope these settings are also for version 12, but probably something similar is available, you need to look around in that dialog box.
