you can determine which map the page is configured to display by looking for the ID of the map div. if the page is configured to show the addresses from the wagmp_map_5.php file, the map div will look like:
<div id="wagmp_map_5"></div>
in the head of your apge, there will be code to attach the map file, similar to:
<?php include("google_javascript/wagmp_map_5.php"); ?>
in your case, you also have lines to attach the other map files:
<?php include("google_javascript/wagmp_map_3.php"); ?>
<?php include("google_javascript/wagmp_map_4.php"); ?>
<?php include("google_javascript/wagmp_map_5.php"); ?>
delete the lines that attach wagmp_map_3.php and wagmp_map_4.php, leave the one that attaches wagmp_map_5.php
