One of the most difficult part of coding in any scripting language is picking apart the value of the variables that are passed through forms, either explicitly or inherently. Placing the following segment of code on the CALLED page (the page that processes the form's information) will list all of the variables that have been passed in your form from the CALLING page (the page that has the form on it)
<cfoutput> <!--- (if you are not already in a cfoutput area) --->
</cfoutput> <!--- (again, if you are not already in an output area --->
Place this in the page body of your called page before any processing is done. The code is a simple while loop that traverses the ColdFusion environment has for form.variables help you determine what is and is not being sent to your page.
