It’s working like a charm. Thank you so much for your time Tareq. Apparently I was not careful enough when I read your developer documentation.

But this code is for saving the data on the new posts.

My other concern is that your Google Maps box will not display the pronamic data input in the previously created posts and I can’t get that through your address finder. Also I need to use some advanced functions of Pronamic GG Maps like the geocode/reverse geocode buttons.The data is saved (I can see it in the back end form) but it is not displayed on the front end form when you reload it. Is there a problem with the get_post_meta() functions here?Thanks a lot for your help, I’m really stuck with this.
