I've tried a number of different navigation XSLT scripts but I can't seem to get it working. I haven't used XSLT much but this mostly comes from somewhere else. The pages just don't appear in the site anywhere. Along with this script there is a Macro control in the master template and two fields in each page called Menu Name and Show In Menu. Any help would be greatly appreciated
