Hi Chris,
I made this post last time as well (under blrboston) but just bought the 3 pack again for another website project. It seems that I still cannot choose the MapPress address from multiple custom fields as described above. I took a look at what you mentioned in regard to save_posts and am still trying to work through it, but it is a bit complex for my understanding. Have you implemented a less obvious way to do this in MapPress? If not, could you please give a bit better perspective on how to go about it?
This feature is even more important for the client I’m working with now and any help would be very greatly appreciated!
