well, one thing I can see from a quick look is that in your code you
are trying to load two different versions of jquery itself
> <script src="../scripts/coda_slider/jquery-1.2.1.pack.js" type="text/
> javascript"></script>
and
> <script src="../scripts/fancy_box/jquery-1.3.2.min.js" type="text/
> javascript"></script>
it's true that many plugins come with a version of jquery included in
the download but it doesn't mean that you have to use them all, mainly
if you want to use different plugins altogether. In this case I would
recommend you to use the latest version of jquery (loaded once and at
the top) for all your plugins.
I have a site running with a slider and some links open in fancybox
without any conflict
