I've been practicing nested lists on a very long unordered list. Out of all the ones I did, I am down to FOUR errors in validator! (Amazing. Don't know how I did it, LOL.) All the errors read: "document type does not allow element "UL" here; assuming missing "LI" start-tag <..ul> " The problems occur when I'm switching in and out between "levels" of my sitemap. So.... 2nd or 3rd tier <..ul> <list item for the Index Page of this folder <a=href="full/url/index.htm">Title</a> <...ul> ---<list item ><a=href="whatever">Title</a> ---<list item ><a=href="whatever">Title</a> </ul> (switch back to the left for another index before another nested list) <..ul> <list item for the Index Page of this folder <a=href="full/url/index.htm">Title</a> <ul> ---<list item ><a=href="whatever">Title</a></li> ---<list item ><a=href="whatever">Title</a></li> </ul> Real example of one error one the first ul line below.: .<..ul> <...li><...a href="http://freepages.genealogy.rootsweb............htm">Index to ....</a></li> <...ul> <...li><a href="http://freepages.genealogy.rootsweb......htm">Fort Pitt ....</a></li> <...li><a href="http://freepages.genealogy.rootsweb......htm">Pitt Five ......</a></li> <...li><a href="http://freepages.genealogy.rootsweb.....htm">Faces of ...</a></li> </ul> </ul> (switch back next) <...ul> Begin another set with the folder's "index" page at the same level as the first one and with one or more li elements in it. etc. etc. <...ul> Barry wrote (something anout ??) that needs done with li and li when doing the nested part. I didn't understand that part and don't know how to word it here except that it's after a nest without a closing li. I first focused on getting the ul structure. So the errors are probably that I didn't put the li and /li's in the right places after the index that starts a new nest?? But everything has worked except in the 4 instances. How do I figure out the pesky additional li's that I am probably missing? And how do I figure out the 4 errors of "does not allow element "UL" here; assuming missing "LI" start-tag" when all the others written the same way at the same (and other levels) are working fine? (only difference is how many closing uls it needs). I did close the lis except on indexes with nests. Whether I use the ul-page or not, it's been fun and challenging. But now, I can barely see the trees from inside the nested treehouse. Oh--- and on a sitemap, should the pages be in an ol ? Should the entire sitemap be an ol ? Judy
