The page needs to reload for the posted information to get to the map.
you could add an anchor just before the map div:
<a name="myMap" id="myMap"></a>
<div id="wagmp_map_1" style="width: 400px; height: 400px;"></div><div id="wagmp_directions_1" name></div>
and change the forms action to go to the anchor:
<cfform id="address" name="address" method="post" action="#myMap">
This will cause the page to scroll down to the anchor when the form posts.
