Dear All - Can anyone help?

I have created a spry gallery page with a dropdown to a number of different
categories...

http://aster.rhul.ac.uk/STAR/galleri..._prototype.php

I want to be able to add links on another page that will automatically load a
particular gallery from this page, i.e. select a particular category to be
displayed from a link on another page.

I was imagining that the links might be in the form
"http://.../gallery_prototype.php?sitename=Ireland%20(Delta)" or similar, and
was looking at the "Using Spry Data with URL params" code, but can't seem to
get anything working...

I have seen this post:

but couldn't get it to work...

I have based my gallery on the standard spry gallery (have I made a mistake by
doing this?)

If you could help I would be most appreciative...

Many Thanks

James
