Javascript window.location only works once!!

I have a store locator page.  Testing on IE8.   Clicking on a store name & address paragraph invokes a javascript funtion that diplays a google map.  The map display function sets up a listener function to display the name and address when the icon on the map is clicked.

The map displays at the end of the page.  I want the function to terminate by scrolling to the map.  Everything works great at first, the page loads, I click on a store name, and I'm scrolled to the map.  However, if I scroll back up to the store list and click on another store, the page doesn't scroll (doesn't move at all).  However, the new map has been displayed, and except for the lack of scrolling after the first time, everything works great.

code snippets:
function disp_map( lat, lng, balloon_text) }
    map.addoverlay(marker);  // this causes the map to display
    window.location = window.location + "#the_map";
<p class="store_block onclick="disp_map(34.011285,-118.400275,'balloon text goes here')">
   store name<br />
   address<br />
  phone<br />
//  more stores go here
<a name="the_map></a>
<div id="map"></div> // the map is displayed in this div

try changing this:

<a name="the_map></a>

<a name="the_map" id='the_map' tabindex='-1'></a>

AND immediately after:
 window.location = window.location + "#the_map";

Thanks for your quick reply. It didn't work, but I paid more attention and noticed something interesting.
The url window at the top of my browser has the following:
After I display the map the first time:

after the second time:
the concation continues to repeat as I click on more stores!  That explains why it doesn't scroll after the first time, but doesn't tell my (I'm a javascript novice) how to get it to work correctly.
OK, then instead of:
 window.location = window.location + "#the_map";

 location.href = location.href.substring(0, location.href.indexOf("#") ) + "#the_map";
