Cannot open google map marker from sidebar list

I am working with the v3 API and trying to recreate the Store Locator sample (which is v2). I like the way the v2 version works vs the same article changed for v3 API. I have everything working with one exception: when I click the location result it does not open up the marker in the map for that location. Here is my code. I think the problem exists in the CreateSidebarEntry() function. Any help would be greatly appreciated! (you can see it in action here: http://www.webworksct.net/clients/ccparking/partners3.php - just enter "orlando" in the search box and click search to get the results, then click a location in the list on the right...nothing happens).

return markers[markers.push(marker)-1];

works and keeps your markers array intact

I found the answer.

In this bit of code:

var marker = createMarker(latlng, name, address);
     bounds.extend(latlng);

var sidebarEntry = createSidebarEntry(marker, name, address, distance);
     sidebar.appendChild(sidebarEntry);

I was calling createMarker to populate the marker var. I found that it wasn't populating.

In the createMarker function, I needed to make a change so that the function returned a value: markers.push(marker); was changed to return marker; and voila!
