Here is a sample database I created. https://www.dropbox.com/s/aeloxf494tj9yr4/GoogleMapsPinSample.fmp12?dl=0
Here is a updated copy of the contacts starter solution that I modified the custom function because it would not display correctly on an ios device. This starter solution is from FM13. The issue is still in FM14. I don't know if there is any difference between 13 and 14, but if there is you can copy the GetMap Function to Contacts solution in FM14. https://www.dropbox.com/s/ddaqb3nj0psftg8/Contacts.fmp12?dl=0
Both have urls that work.
Thanks for posting the Dropbox link but I'm on a network where I cannot access files from Dropbox. I don't need the whole database just the change. Can you post the url that you got to work, like I did above. Much appreciated!
