Jeremy Upton uploaded a CF for easy formatting of code for a web viewer showing an embedded Google map that used address information. Here is a modified variation that uses latitude and longitude information if you have it.

I also added a parameter so you can name the web viewer object anything you wish and pass it via the custom function.

Update to add code to center the maps on the coordinates in case the coordinates do not correspond to an address. otherwise the map will center on the nearest city or county seat, which is not always helpful. A green arrow will show your point, the A marker will show the nearest address, city center or county seat, whichever google can determine first.

The correct spelling is Latitude, not Latitute.

Can this be applied to multiple Lat/Long locations?

Hy there: I'm trying this function and it very usefull. I'd like to increase the latitude in amounts of 0,0001 in the latitude (for exemple), within a script. But when i just add that amout in the latitude with a script, the value changed from 37.66395 to 3766395,00001, not the way I intend, because of the point (and i need to use ,). How can i avoid this? Thanks

Hi Yvonne!! This function itÂ´s great! Sorry for my english, thatÂ´s not so good than your function. IÂ´m a Filemaker Developer, and I need to print in PDF the map generated with your Fn, but I canÂ´t do it... I understood that I need to convert the map in an image... Â¿Can you help me? Thank you a lot, Jorge

Do you have to comment out all the quotes from <script type= ?
