[OpenLayers-Users] Beginner issue

[ethio info]

Hi, Please take a look at this site:
http://projects.latimes.com/mapping-la/neighborhoods/.
I have copied the source and cleaned it up of ads and so forth and have put
in my data and I just can not see the overlay on the Google map.
I will include the changes I made below.  The only thing I can think of that
is blocking my overlay is the bounds.  Basically, I want the country of
Ethiopia.
Just to complicate things further, my overlay was showing when I did not use
a spherical mercator projection but the overlay matched what is in Google
maps ONLY when I zoomed in.
so after reading some of the issues some people had, I figured I should use
what is in the Mapping LA w/minor changes.
Can someone suggest a solution?  BTW, the overlay switch works and gives my
overlay as a check box option to click on but it is not displayed on the
Google map
Here are my changes to the Mapping LA Neighborhood source:

var max_extent = new OpenLayers.Bounds(860986,-4383204,5870363,3600489);
    index_map.addControl(new OpenLayers.Control.LayerSwitcher());
