One of the guys here came up with a hack to do this. Wrap an Evaluate
around the expression, and that seemed to work for us in a similar
situation. We'll not sure if this is clean ColdFusion or not, but it seems
to get the job done.
Here is a sample:
<cfset tempvar='full_name_'&'#PersonsAttending)#'>
<cfset tempcomment='#Evaluate("#tempvar#")#'>
Now tempcomment contains the value that full_name_3 from the previous page
did. Assuming PersonsAttending is 3.

>
>
> I've got a form that is dynamically created based on how many people are
> being registered for an event. For example, if a person wants to
> register 4
> people, I use <CFLOOP> to create a form with fields for the entry of 4
> peoples' names. I.e.:
>
>
>
> <html>
>
> Person 1: <input type="text" name="full_name">
>
> <cfif PersonsAttending GT 1>
>
> <cfset loopnumber = (#URL.PersonsAttending# - 1)>
>
> <cfloop index="PersonsAttending"
> from="1"
> to="#loopnumber#"
> step="1">
>
> Next Person: <input type="text" name="full_name_#PersonsAttending#">
>
> </cfloop>
>
> </cfif>
>
> </html>
>

> The effect of this is that the name of the form fields changes during each
> step of the loop, such as:
>
> full_name_1 (where the index of "PersonsAttending" is 1)
> full_name_2 (where the index of "PersonsAttending" is 2)
> full_name_3 (where the index of "PersonsAttending" is 3)
>
> and so on.

> The <cfmail> looks something like this:
>
> <html>
>
> <cfmail to="me" from="you" subject="Registration">
>
> Registration Received for:
>
> #FORM.Full_Name#
>
> <cfif PersonsAttending GT 1>
>
> Other People Registered:
>
> <cfset loopnumber = (#URL.PersonsAttending# - 1)>
>
> <cfloop index="PersonsAttending" from="1" to="#loopnumber#" step="1">
>
> #FORM.Full_Name#_#PersonsAttending#
> ^^^^^^^^^^^^^^^^^^^
> </cfmail>
>
> </html>
