Referring to a variable as a String

I have a form that consists of a dynamically-generated set of form fields. Thus, I have fields of unknown nmae coming into my form-processing page.  (they're identified with an ID number).  

How can I get the value of these form fields, if I can't hardcode the names of the fields ahead of time?

e.g. several sets of radio buttons are created, each set having a unique name identifier.  I can know the names of them coming in via hidden form fields generated later, but I can't access the values of the fields, since I can't refer to FORM.#myval# or something like that....

Increased points to 300...

Maybe if I just had the query string, I could get what I needed....how can I get that?  (This is a result of a POST operation)

Use the Form.FormField field which is passed from all forms....

Insert this code on your action page

<CFIF ISDefined("Form.Fieldnames")>
  <table border="1">
    <CFOUTPUT>
      <CFLOOP Index="FieldName" List="#Form.Fieldnames#">
        <td>Form.#FieldName#</td> <td>#Evaluate(FieldName)#&nbsp;</td></tr>
      </CFLOOP>
    </CFOUTPUT>
  </table>
</CFIF>

Note: that radio buttons and checkboxes will not return a field if they are not selected/checked, so have a default radio button checked.
