Hi Jørgen, thanks for your response. Forgive my lack of detailed knowledge. I'm straying in to this world and don't have a great deal of experience to draw on as you can tell.
I have changed a bunch of things since you repsonded but I'm curious to know first of all how you know that the javascript plugin I'm trying to use is 'not found'? Would be very helpful for me to understand exactly how you debugged that.
However, I will try to take your advice about wrappers etc although having read the wordpress article, I still don't understand what I'm doing. I know it's not quite on topic, but is it perhaps the 'src' path that is wrong when I try to run this?
Also, if I don't put that in the header can I simply use the 'JSS' pane underneath the view query section in my view configuration page?
Of course that would be easier, but I was under the impression that I have to ready the document for the javascript to work later on. Is that right?
With a little knowledge of how to place the scripts in the right place, I will be able to tweak out my filter forms.
Andrew
