<P>Hi,</P>
<P></P>
<P>I am trying to write a mapfile that will use javascript to dynamically sent
EXTENT values to a .map file via POST parms. Concretely, when I select a county
in MN from a dropdown, I want to send the appropriate values for the EXTENT bbox
so that the selected county is rendered in it's specific bbox.</P>
<P></P>
<P>The beginning of my mapfile looks like this:</P>
<P>---</P>
<P>MAP</P>
<P>IMAGETYPE PNG</P>
<P>EXTENT %xmin% "%ymin%" "%xmax%" "%ymax%"</P>
<P>SIZE 880 660</P>
<P>...</P>
<P>---</P>
<P></P>
<P>the url i issue is:</P>

<P></P>
<P>the error i get is:</P>
<P>getDouble(): Symbol definition error. Parsing error near (%):(line 7) </P>
<P></P>
<P>line 7 is the EXTENT line.</P>
<P></P>
<P>So, my questions are:</P>
<P>1. Does MapServer support variable substitition for extent values? If so,
what am i doing wrong? If not, how do I dynamically set the extent for
dynamically selected polygons with different bboxes?</P>
<P></P>
<P>2. Is there a better way to set the bbox rather than send it precalculated
values in a GET? It seems natural that I should be able to leave the EXTENT line
off and a default of the smallest bounding box that works for the returned
geometry would be returned as a default.</P>
<P></P>
<P>tia,</P>
