How do I use the form checkbox value?

Question

I'm creating a form that has multiple checkboxes. I want to
use ActionScript to update a text box/area with the values each
checkbox as the checkbox is selected. Any ideas on how I might do
that?

Answer 1

I figured out how to do it using both the last poster's
comments, and some others that I found.
A form is created using cfform format=flash.
A cfinput text box is created and flagged as not visible.
The "invisible" input value is set after a cfoutput
query="xxxx"
is completed.
Since I'm using the query to do double duty, I have a group
set.
My "second" group is the one on which I wanted the check
boxes to
be created dynamically.
I set a counter, and kept track of when a check box was
created.
The value of the counter was eventually set as the value of
my
first "invisible" text box.
Here's the code:
<cfformgroup type="horizontal" height="1" visible="no">
<cfif #BoxCount# GT 0>
<cfoutput><cfinput name="BoxQty" type="text"
value="#BoxCount#" visible="no" size="3"></cfoutput>
</cfif>
</cfformgroup>
Each check box was given a unique name, text + counter.
ex. camp#BoxCount#
A corresponding "invisible" text box was created:
ex. cost#BoxCount#
This way I can test if the check box "value" is true/false,
and
set a cost accumulator to the proper cost.
My cfsavecontent code looks like this:
// COST TOTAL
var a = Number(BoxQty.text);
var i = 0;
var j = 0;
var u = 0;
var x = 0;
var s = "";
for( i=1; i<=a; i++ )
r = "camp"+i;
if( eval(r).value ) // just like the JS eval()
// box was checked, i.e. is "true"
s = "cost"+i;
j = Number(eval(s).text);
if( j > 0 ) x = x + j; // add to the total accumulator
//campCost is the cfinput text box used to display the total
cost.
campCost.text = 0;
if( x != 0 )
campCost.text = "$" + x + ".00";
