Google Maps Pin Solution
I have seen this question asked several times (Using Google Maps Pins). I came up with a pretty easy solution, which was right in front of me. The GetMap function which includes the google Maps url has "Marker=". Yes that is it, for each marker (Pin) just add another "Maker=" with the address. I created a sample app in FMP 12 advance. I used a calculation instead of a function for those that don't have advance.
Use and enjoy.
