[UMN_MAPSERVER-USERS] dBox CGI point query

[Lawrence Hartpence]

Hello,

I recently posted an issue I was having with dragging a pan using dBox.  I now 
have that isue resolved, but now I have lost teh ability to query by a single 
mouse click.  Selecting by box works fine, but not by point.  When I click a 
point, I get the error:  mapserv(): Web application error. No way to generate 
a valid map extent from selected shapes.

Any help would be greatly appreciated!!

Here is the URL for my website:
http://71.7.3.212/JasperMaps/Parcels/goParcels.html

Once you initiate the map by clicking the "County View" button, zoom a small 
box, click the "i" next to teh parcels layer and click on a parcel.  

Here is the portion of my HTML that sets up the set box parameters:

function main_setbox(minx, miny, maxx, maxy) {

      var MSMode = document.the_form.mode.value
      var zoomVal = document.the_form.zoomdir.options
[document.the_form.zoomdir.selectedIndex].value;
        //document.the_form.zoomdir.value = zoomVal;
//alert(zoomVal)
    if(MSMode == 'browse') {
        
        if (zoomVal == 1 && minx != maxx && miny != maxy){
                        
         document.the_form.imgbox.value = minx + " " + miny + " " + maxx + " " 
+ maxy;
         document.the_form.submit();
                
           }
      else if (zoomVal == 1 && minx == maxx && miny == maxy){
          
         document.the_form.imgxy.value = minx + " " + miny;
         document.the_form.submit();
         }
        if (zoomVal == 0 && minx != maxx && miny != maxy){
           ZoomMode();
                
           }
      else if (zoomVal == 0 && minx == maxx && miny == maxy){
          
         document.the_form.imgxy.value = minx + " " + miny;
         document.the_form.submit();
         }

        if (zoomVal == -1){
          
         document.the_form.imgxy.value = minx + " " + miny;
         document.the_form.submit();
         }
       }

     if (MSMode != 'browse' && minx != maxx && miny != maxy) {

         document.the_form.imgbox.value = minx + " " + miny + " " + maxx + " " 
+ maxy;
         document.the_form.submit();
           }
     if (MSMode != 'browse' && minx == maxx && miny == maxy) {
         document.the_form.imgxy.value = minx + " " + miny;
         document.the_form.submit();
         }
        
   }
