Thank you for your post.
I just used a couple examples from Google's static maps API (http://code.google.com/apis/maps/documentation/staticmaps/) and they all work with the Open URL step in FileMaker Go.
On Page 14 of the FileMaker Go Development Guide (http://www.filemaker.com/support/product/docs/filemaker-go/fmgo_development.pdf), it states:
"The Open URL script step using a Google maps URL will open a browser, and then choosing Open in Safari will open the Maps application."
If you want to provide the link, I'll try it here.
When I use the URL script step with this url in FMPro 11, my browser opens to a fully functioning Google Maps page:
I get the error when I try this with FMGo on my iPhone.
Now it works! I loaded Google maps directly from Safari and then logged into my google account. Then it worked, just as advertised. I don't know if logging in was required or if there was some other problem going on last night, but now all is cool.
Again, thanks for your help.
