i updated the /webassist/google_javascript/wagmp_map_5.php file to correct the problem.
in the searchCache function, i changed the last line from:
return '';
to:
return coordinates;
function searchCache(searchStr, zip) {
var xmlDoc = null;
var coordinates = '';
xmlDoc = getHTTPObject();
if(xmlDoc) {
xmlDoc.onreadystatechange = function() {
if(xmlDoc.readyState == 4) {
var x = xmlDoc.responseXML.getElementsByTagName("geocode_entry");
var geocode, id;
searchStr = searchStr.replace(/,/g, ''); //remove commas
for (i=0; i < x.length; i++) {
id = x[i].getAttribute("ID");
if (id == searchStr) {
coordinates = x[i].getElementsByTagName("geocode")[0].childNodes[0].nodeValue;
return coordinates;
}
}
}
}
xmlDoc.open("GET", "webassist/_promaps_cache/_promaps_geocache.xml", false);
xmlDoc.send(null);
} else {
return '';
}
return coordinates;
}
