Popups

I'm trying to setup my map to display popups, and it currently works, but I don't know how to make multiple nodes appear in the popups...

According to this site, popups work with clustering so that when you click on a cluster's marker, you can apparently scroll through teasers of the nodes within that cluster. However, when I enable clustering, markers disappear altogether...

What I'd prefer, is that markers are for taxonomy terms and when you click on a term's marker, you can scroll through the nodes for that term in the popup. Is this possible?

My test site can be viewed here: http://maptest.gudo.netengine.com.au/
The Taxonomy Map is a working map using the tooltips functionality. The Popups Map is what I have the issue with. Ideally, I'd like it to work the same at the Taxonomy Mpa, just showing the nodes in a popup rather than on a separate page.

Any assistance would be much appreciated!

Ok, I've worked out how to show the nodes in each term in the popup (using relationships and grouping), but I can't seem to get the popups and scaling markers working at the same time...

Any idea what I need to do to get both scaling markers and popups working on the same map?
