I got it working thanks to elxiduppy on another forum I post on alot.
Here is the code in case anyone else needs it. Please keep in mind
that I also add a description to the marker and I also check that. So,
if you have two markers that are in the same spot but different
descriptions, they will be seen as different.
//this function keeps an array of markers
//if the marker is on the map then it removes
//the marker. Otherwise it adds the marker
function addUserMarker(lat, lon, desc) {
var inMap = false;
var count = 0;
var loc = new GLatLng(lat, lon);
while (inMap == false && count < arrOfMarkers.length) {
//if the lattitude and longitude are on the map
//and the descriptions match each other then it is an
//existing marker.
if ((loc.lat() == arrOfMarkers[count].getLatLng().lat())
&&
(loc.lng() == arrOfMarkers[count].getLatLng().lng())
&&
(arrOfDesc[count] == desc)) {
inMap = true;
break;
}//if
count++;
}//while
if (!inMap) {
var marker = new GMarker(loc);
arrOfMarkers.push(marker);
arrOfDesc.push(desc);
GEvent.addListener(marker, "click", function() {
marker.openInfoWindowHtml(desc);
});
map.addOverlay(marker);
map.setCenter(loc, map.getZoom());
}//if
else {
map.removeOverlay(arrOfMarkers[count]);
arrOfMarkers.splice(count, 1);
arrOfDesc.splice(count, 1);
}//else
} //addUserMarker
