[mapserver-users] MapServer ITEMQUERY

[MapServer Newbie]

Hello All!
I am a MapServer and Ubuntu newbie, trying to use the example code from:
Bill Kropla, Begining MapServer Open Source GIS Development
http://www.apress.com/book/downloadfile/2213
Chapter 5, fourth.map fourth.html...
the QUERY and NQUERY modes work (although the TOLERANCE is not changed from the value in the .map file when he tries to use [map_Cities_tolerance] in the URL) but I am unable to get the ITEMQUERY mode to work at all. I am using his example of: qlayer=Cities qitem=COUNTRY qstring=/US/
I have also tried the non-regular expression query items: US 'US' "US"
I always get the following error message:
mapserv(): Web application error. Parameter 'qstring' value fails to validate. msValidateParameter(): Regular expression error. Parameter pattern validation failed. 
the URL is:
http://localhost:8080/cgi-bin/mapserv?
zoomdir=0&zoomsize=2
&layer=Cities&layer=Countries
&mode=itemquery&qlayer=Cities&imgbox=&qitem=COUNTRY&imgshape=&qstring=%2FUS%2F
&mapshape=&map_Cities_tolerance=0&shapeindex=&map_Countries_tolerance=0
&imgxy=320+160&imgext=-180.000000+-89.859155+180.000000+89.859155
&map=%2Fhome%2Fgeorge%2Ffgs%2Fapps%2Fgmap-demo-cvs_MS_VERSION_54%2Fhtdocs%2Ffourth.map
&program=mapserv&slayer=Countries&previousmode=[previousmode]&savequery=true

I am running MapTools fgs-mapserver_extended_5.4.2-fgs_9.5-linux-i386.bin on Ubuntu 9.04 Desktop

Anyone have any idea why ITEMQUERY doesn't work?
Anyone have an ITEMQUERY example that does work?
