There are previous topic and next topic button in the navagation bar.
When I click the "next topic" button , I want to go to the next topic in my help system (WebHelp Pro), but it does not work. Any suggestions?
Are you talking about the buttons for the browse sequences (buttons above the TOC) or about something else? If you're talking about the browse sequence buttons, you need to create a browse sequence with the Browse sequence editor in the Tools menu.
In addition to William's excellent advice, the link below may help.
