Virtual Spatial Data

[Lawrence Hartpence]

Hello,

I am learning about using Virtual Spatial Data in Mapserver.  I added an
Access table with xy data.  It displays fine and labels fine, but when I try
to query it, I get the following error: "mapserv(): Web application error.
No way to generate a valid map extent from selected shapes."   This happens
when I try to click on the point.

Here the URL:
http://gismap/JasperMaps/cgi-bin/mapserv.exe?&program=%2FJasperMaps%2Fcgi-bin%2Fmapserv.exe&map=C%3A%5CInetpub%5Cwwwroot%5Cmapdocs%5CSeptic.map&zoomsize=2&layers=ortho+Septic+Parcels+Lots+ROW+Survey+Section+Sub+ParcelPt+Water+Shields+Highways+Roads+Watershed+County+Towns&mode=browse&slayer=Parcels&imgxy=320+240&imgext=1680507.39+547052.00+1844030.00+680312.51&mapshape=&imgshape=&imgbox=&qstring=&qlayer=Parcels&qitem=&shapeindex=&savequery=

Any ideas what I am doing wrong?

Here is an excerpt from my map file:
