Hola Derek,
That's great!, your error points to the projection (SRS) that it is required and also
something called version 1.1.1 that it is normally added in the MAP file when using
Mapserver. Are you using Mapserver? if so, you should read this one:
http://mapserver.org/ogc/wfs_server.html, these instructions are useful for WFS layers,
but WMS is a bit more problematic, try this one also:
http://mapserver.org/ogc/wms_server.html. I think with both of them you will start
understanding where the problem is, that it is basically adding the "wms_srs"
flag (if using Mapserver) and adding the right projections. If your raster is in UTM, you
have to play a bit, probably assigning the right UTM SRID (check for getting ideas:
http://stackoverflow.com/questions/1541202/how-do-you-know-what-srid-to-use-for-a-shp-file)
plus the 4322 as you already did (or as it appears in the WMS web I put above).
Hope this helps!, cheers

Subject: Re: [OpenLayers-Users] wms layer over openstreet base map
Hola Gery,
That does help and I have been able to narrow the problem down a bit
more. I think this has to do w/ the fact that I am attempting to
load a wms layer and there isn't an entry for the item in epsg
file. I gathered this from the following page
I have now added the epsg for 900913 but I am still having an
issue. I was able to get an error back from the wms server which
is:
<?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?>
<!DOCTYPE ServiceExceptionReport SYSTEM
"http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd";>
<ServiceExceptionReport version="1.1.1">
<ServiceException code="InvalidSRS">
msWMSLoadGetMapParams(): WMS server error. Invalid SRS given : SRS
must be valid for all requested layers.
</ServiceException>
</ServiceExceptionReport>
Thanks,
Derek

There is a lot of stuff about google maps and openlayers and
projection, just google them.
Hope this helps,

sorry!, I meant "4326" instead of "4322" =)
