I'm not certain what you mean by "Why isn't it working ?"
The navigation structure of your sites is working, the links I tried all lead to their respective pages and the banners lead to your alternative sites.
Could you be a litte more specific in what it is you are looking for here ?
I've not checked all pages and links so perhaps I'm missing something obvious here.
Things seem to be going along nicely though.
Incidentally, I like your layouts.
Your use of PHP was unexpected and unless your site(s) require the events calendars you might want to re-think that side of things. I realise that everything starts small, but nothing looks quite so forlorn as a well implemented site that potentially offers lots of content but that content is not actually there.
An events calendar, like a discussion or bulletin board, needs a lot of very careful consideration before implementing it.
Anyway, post again with some specifics and we will try and offer more appropriate feedback.
The links, for those who may have missed them above, are as follows:
