Google Maps Api v3: Info window displaying same information for all the markers on the map

I'm working on this code for a certificate program, I tried to get some help from the instructors but they don't seem familiar with Google Map Apis and the requirement is to display multiple markers from addresses stores in an XML file once a search is performed, i.e I look for John, I get his markers in addition to markers for all of the people whose address is stored and specified in my XML file. So the goal is to be able to display say 5 markers for 5 people and their respective info windows.

I'm able to get all markers to display once a search is performed, I can also get the info windows but the info displayed in all info windows is the same in all markers, it displays the information for the name searched for. You could if you want test with the name Larry, zoom out to other markers and see that they all display the same name. I have no idea why? When I looked at fixes, I found nothing for google API v3 only stuff link a bindEvent for the Api v2. Any help would be highly appreciated, I don't know how to stop the for loop from making all the info windows the same. Thanks. The code is bellow:
