simple query on shapefile

[Dylan Beaudette]

greetings,

i am trying to query a simple map of california counties here:
http://169.237.34.168/~dylan/mapserver/ca_county/map.html

however, when the mode is set to nquery, a click on the map results in
the following error:
msQueryByPoint(): Search returned no results. No matching record(s) found.

i have tried looking over some of the example mapserver  pages, but
cannot figure out how the query mechanism really works...

any points on how to get a working query system setup?

here is the source for my .map file:

http://169.237.34.168/~dylan/mapserver/ca_county/ca_county.map

any ideas?

thanks in advance!
