What I am trying to accomplish is getting an interactive map that shows pins based on custom fields associated with it.
So, if I have pins for New York, Albany and Boston about ball parks, football fields and baseball fields, I am trying to pair the mashed up map with check boxes to show any of both or only one and any combination in between.
So far I tinkered with categories and with this http://wiki.geo-mashup.org/guides/custom-marker-depending-on-a-custom-field-value but I have no idea on how to tie the two in so I can accomplish the same category check boxes effect with custom fields. Sure I could use categories. On a fresh installation I would, but this is far rom fresh and I use categories in a non canonical way.
Can you help? Pointers? Thanks
