I want to check to see if any of the existing markers match the latlng of the new marker and if so then merge the info window/tooltip text.
This is what I tried to do:

I tired to take this working example found here http://www.geocodezip.com/SO_OverQueryLimitB.html and add the following code into it:
///get array of markers currently in cluster
var allMarkers = mc.getMarkers();
//check to see if any of the existing markers match the latlng of the new marker
if (allMarkers.length != 0) {
for (i=0; i < allMarkers.length; i++) {
var existingMarker = allMarkers[i];
var pos = existingMarker.getPosition();
if (latlng.equals(pos)) {
text = text + " & " + content[i];
}
}
}
So that the final result when you click on a marker that has the same latlng it would display one info window with the merged text like the one found here http://maps.caseypthomas.org/ex/MarkerClustererPlus/exCoincidentMarkers_SharedInfowindow_wGeocoding.html See it shows the number 4 but displays only 3 markers that's because the one on the right side is merged with another one behind it and when you click on it it shows you the text for both. only I would like to use geocodezip's example and work on top of that since I already have the cords and don't need google to go get them for me. Thank you for just reading this LONG Question if noting else..
and Thank you 1Mill X over if you can help me find a solution.
Thanks again!!!

You need to :
add the markers to the MarkerClusterer (and format your code so it is easier to read...).
function createMarker(latlng,text) {
var marker = new google.maps.Marker({
position: latlng,
map: map
});
///get array of markers currently in cluster
var allMarkers = mc.getMarkers();
//check to see if any of the existing markers match the latlng of the new marker
if (allMarkers.length != 0) {
for (i=0; i < allMarkers.length; i++) {
var existingMarker = allMarkers[i];
var pos = existingMarker.getPosition();
if (latlng.equals(pos)) {
text = text + " & " + content[i];
}
}
}
google.maps.event.addListener(marker, 'click', function() {
infowindow.close();
infowindow.setContent(text);
infowindow.open(map,marker);
});
mc.addMarker(marker);
return marker;
}
