Linking to separate html projects

Hi All,We have decided that instead of exporting to CD/DVD, we need to export to html for future hosting on the WWW.However, as all of you experienced Lectora developers know, there are a number of factors to take into consideration. I’ve not worked with html yet, and my question concerns one of these factors. I'd be very grateful for any advice on the matter, as I feel I may still be thinking too much in terms of exe files! Description :Say I have two chapters each with two sections and a home page linking to them. Each section is to be an independent lectora project. The number of projects would thus be 5 :1. Home 2. Chap1, Section 13. Chap 1, Section 24. Chap 2, Section 15. Chap 2, Section 2Obviously the Home/index.htm is the first page to appear and contains links to the others. When a link, say Chap1, Section 1 is clicked, the home page closes and the target (Chap1, Section1) appears. Now Chap1, Section1 in turn contains links to an html page which contains video presentations, and in the CD version, would be located in the ‘extern’ folder. However, when I export my project as html, I cannot get this link to work, even if using a simple html page with nothing but text on it.What I did was : 1. create a one page lectora project, with a link to a simple html page containing no more than a few lines of text. This simple html page is in the extern folder, and the link is via the ‘Go to > Webpage’ hyperlink. When I preview the project, it works fine.2. When I export my project to html, and copy the ‘extern’ folder into the exported project folder, I am unable to get it to work. End of DescriptionMy logic for attempting the above is to have the system as modular as possible – i.e. a number of different self-contained units linking to each other rather than a clumsy, large structure. This logic may of course be unsound. What do you think? Any suggestions for a better way of structuring this? We are at the very start of the redesigning process, and have to tackle these issues before going any deeper.Many thankscas
