Image map generation

[Ian]

I'm able to get query results with the following CGI controls:

**<form name="map" method=GET action="/cgi-bin/mapserv">
<input type="hidden" name="map"
value="/var/www/html/maps/queryResultsMap.map">
<input type="hidden" name="qlayer" value="worldCities">
<input type="hidden" name="mode" value="nquery">
<input type="hidden" name="mapext" value="-180 -90 180 90">
<input type="hidden" name="scale" value="6500000">
<input type="hidden" name="searchmap" value="true">
<center><input type="submit" value="Query Results Only"></center>
</form>

However when I make slight modifications to try to create an image map of
the results with these controls:

<form name="map" method=GET action="/cgi-bin/mapserv">
<input type="hidden" name="map" value="/var/www/html/maps/queryMap.map">
<input type="hidden" name="qlayer" value="worldCities">
<input type="hidden" name="mode" value="nquery">
<input type="hidden" name="mapext" value="shapes">
<input type="hidden" name="mapsize" value="500 500">
<input type="hidden" name="mapxy" value="20 20">
<input type="hidden" name="imgext" value="0 0 500 500">
<input type="hidden" name="scale" value="6500000">
<input type="hidden" name="searchmap" value="true">
<center><input type="submit" value="Query Image Map"></center>
</form>

each result's coordinate values goes to "-2147483648,-2147483648,7"

Am I missing something? I'm trying to pass the same parameters that we pass
in our web application of MS, but to no avail so far.
Thank you.
