Presumably the code as written to html here has '../LearningSolutions/' because the menu is situated in the 'incl_files' directory and therefore needs to refer to directories one level higher than itself. So this code works fine directly from the upnav.htm includes file.
Thanks again for trying. The problem is still unresolved.
The flaw in this logic is as follows:
The menu code works fine in the same directory as the include file, it also worlds one level above. It simply does not work two levels above.
