<DIV><FONT size=1>Hi folks,</FONT></DIV>
<DIV><FONT size=1>I have an airport layer with different classes of airports
within it determined by a SYMBOL attribute in the shape file. I would like to be
able to choose the Attribute to display at run time by feeding the labelitem i.e
FAAID or Airport Name from a dropdown list box on my html form.
</FONT></DIV>
<DIV><FONT size=1>In other words, I want the user to be able to diplay the
Airport name if they want, or the FAA Id, etc... chosen from a dropdown. Can
this be done? </FONT></DIV>
<DIV><FONT size=1></FONT> </DIV>
<DIV><FONT size=1>I haven't seen a question on this or an example of this in the
archives. </FONT></DIV>
<DIV><FONT size=1></FONT> </DIV>
<DIV><FONT size=1>Does anyone have an example of doing this and
what variable should I be passing to the map file and what is the syntax of
that, please? Also, any suggestions on the coding of the html drop down? Thanks
for any assistance. Below is a snip of my map file.</FONT></DIV>
