Default Update Google Map API Markers

i'm trying to figure out how to update a map marker for the Google Maps API. i took existing code that works correctly and tried to apply it to my solution but i haven't been able to get it to work... here is the code that works to store new markers (slightly abbreviated)...

Code:
function storeMarker() {
    var getVars = "?species=" + document.getElementById("species").value        
        + "&lat=" + lat;

    var request = GXmlHttp.create();

    //open the request to storeMarker.php on your server
    request.open('GET', 'storeMarker.php' + getVars, true);
    request.onreadystatechange = function() {
        if (request.readyState == 4) {
            //code...
           }
    }
    request.send(null);
    return false;
}
for my solution, i have the following function that is triggered by this code...

<form name="MarkerForm" onSubmit="return updateMarker()">

all of the fields are inside the form and i have confirmed the URL string is formatted correctly with the alert(); below. the updateMarker.php page has been tested independently and works correctly, but when i try to update a marker from the map API it does not update the form data or database record and does not give me any errors. any suggestions? thanks!

Code:
function updateMarker() {
        var getData = "?species=" + document.getElementById("species").value
                 + "&lat=" + lat;

    //alert('updateMarker.php' + getData); <-- this has confirmed the URL string is formatted correctly

    var request = GXmlHttp.create();
    request.open('GET', 'updateMarker.php' + getData, true);

    request.send(null);
    return false;
}
