[Chameleon] Unknown error with msProcessAutoProjection

[Ivan Kautter]

List Subscribers,

I am new to Chameleon.  Glad to have found it.  I have made slight 
modifications to the sample_roi application.  Application produces correct 
map output in general however whenever msProcessAutoProjection is called in 
any php script I get an error of this nature:

Fatal error: [MapServer Error]: _msProcessAutoProjection(): WMS/WFS AUTO 
PROJECTION must be in the format 'AUTO:proj_id,units_id,lon0,lat0' (got ''). 
in 
C:\ms4w\apps\chameleon\htdocs\widgets\ZoomSelectedLayers\ZoomSelectedLayers.widget.php 
on line 111

This was true as well when I had the north arrow widget in the map 
application as well, which I removed to circumvent the problem.

I specify no projection in my mapfile as thus far I have been depending on 
mapserver to choose an appropriate one.  Is this the cause of the problem I 
am experiencing?

I have failed to specify a projection as it is a California State based 
system that I am not sure how to define it for, I assume, PROJ.

Here is the spatial reference for all data used in map as per ArcCataolg:

I would be greatly appreciative of any assistance that anyone can offer.  
Thanks for your time and attention.
