I have a server side image map application that works quite
well. I decided that I wanted to pass more user-generated
information than the coordinates of the click, specifically to add
a set of radio buttons. I'm not sure how to get the value of the
radio button along with the other stuff. Here is my initial html
file:
<title>Map database - Costa Rica point
pick</title>
<h3> Clicking any point on the map will find all maps
at that point.</h3><br>
<INPUT type="radio" name="fuzzc" value="0"> Very
precise
<INPUT type="radio" name="fuzzc" value="3" checked>
Some tolerance
<INPUT type="radio" name="fuzzc" value="5"> Much
tolerance<br>;
<a
href="../pointpick.cfm?hgt=510&prjn=EQ&wid=467&left=-86&right=-82.3646&botdeg=8&topdeg=11.909&lr=deg"><IMG
src="../picpics/costa_rica.gif" ismap width=467
height=510></A>
When it gets to the code in pickpoint.cfm that tries to get
the calue of the radio button, I get
Element FUZZC is undefined in FORMS.
The error occurred in
D:\inetpub\wwwroot\mapsCatalog\test\pointpick.cfm: line 160
158 : <cfset botdeg = #fixparam(URL.botdeg)#>
159 : <cfset fuzzd = abs(topdeg - botdeg) * (fuzzp /
hgt)>
160 : <cfset fuzzq = forms.fuzzc>
I understand that this is happening because I'm trying to mix
2 types of parameter passing, but don't know how to get around it.
