How to get the value of radio button in ColdFusion?

I can't find a simple tutorial to help me do this task. Basically I need to assign the value of radio button and pass it to the next page through session. This is my code for the radio button input.

<input type="radio" name="statReqYN" id="statReqYN-0" value="Yes" checked="checked"> Yes
<input type="radio" name="statReqYN" id="statReqYN-1" value="No"> No

After that, I will set the value of button:

<cfif isdefined("form.newProdYN") and form.newProdYN is "No"> 
<cfset form.newProdNY = "No">
</cfif>

Lastly, I will pass it to the next page of the same session through the submit button:

<cfif not arrayLen(errors)>
<cfset session.checkout.input = {
newProdNY=form.newProdNY}>
<cflocation url="formcomplete.cfm" addToken="false">
</cfif>

But when I try to get the value with #session.checkout.input.newProdYN# in html, the result is undefined. Can anyone help me solve this problem?

Your question isn't very clear as there are variables that are not being shown in your code. Generally, with radio and checkbox fields, your receiving form should have a default value set. I do this by doing something along the lines of:

<cfparam name="FORM.statReqYN" default="no">

This way you can always use the variable. So in your case, I would have this as the whole template:

<cfparam name="form.statReqYN" default="No">
<cfparam name="form.newProdYN" default="Yes">

<form action="" method="post">
    <input type="radio" name="statReqYN" id="statReqYN-0" value="Yes" checked="checked"> Yes
    <input type="radio" name="statReqYN" id="statReqYN-1" value="No"> No

    <button type="submit" name="newProdYN" value="Yes">Submit</button>

</form>


<cfif form.newProdYN IS 'Yes'>
    <cfset session.checkout.input.newProduNY = form.newProdYN >
    <cfset session.checkout.input.statReqYN = form.statReqYN >
    <cflocation url="formcomplete.cfm" addToken="false">
</cfif>

I hope this makes a bit more sense?
