Thanks Jason - but unfortunately the code is now quite different (perhaps things changed with new versions)
The only .js file in the google_javascript folder is wagmp_maps.js which contains only the following code:
window.onunload = function() {
GUnload();
}
/*wagmp_onload*/
if(window.wagmp_map_3) wagmp_map_3();
-------------
I have attached my wagmp_map_3.php file - but that doesn't contain any code similar to the example on the other post.
Cheers
Chris
