How to set cfinput as variable?

Im trying to add some <cfif> statements to my <cfform> via radio button so if someone selects radio button (A) they will see this, if they select radio button (B) they will see something different.

If radio button is not the best way to do this what other option do I have to have an action based event allowing different options for different selections.
<cfparam name="billing_info" type="radio" default="pay_credit">
	Check <cfinput name="billing_info"  type="radio" value="pay_check" />
	Purchase Order <cfinput name="billing_info"  type="radio" value="pay_po" /> 
	Bill Agency <cfinput name="billing_info"  type="radio" value="pay_agency" />
	Voucher <cfinput name="billing_info"  type="radio" value="pay_voucher" />
	Credit Card <cfinput name="billing_info"  type="radio" value="pay_credit" checked="yes"/></td>
    </tr>
  <tr>
    <td colspan="6"><cfif billing_info eq "pay_check">Check <cfelse> -- </cfif></td>

Remember that ColdFusion is a server-side technology.  What you're trying to do is Client-side.

You would need to enable/disable or make visible/invisible additional fields using javascript via the onChange attribute on the check boxes.

try something like this

<cfparam name="billing_info" default="pay_credit">
<cfset payList="pay_check,pay_po,pay_agency,pay_voucher,pay_credit">
<script>
function doPay(f) {
for(var i=0;i<f.length;i++) {
      if(f[i].checked) {
            document.getElementById(f[i].value).style.display='inline';      
      }
      else {
            document.getElementById(f[i].value).style.display='none';      
      }
}
}
</script>
<cfoutput>
<tr>
<td align="left" width="25%">
<form>
<cfloop list="#payList#" index="ii">
<nobr>
<input name="billing_info" id="billing_info" type="radio" value="#ii#" onclick="doPay(billing_info)"
      <cfif variables.billing_info is ii> checked</cfif> />
#ucase(listlast(ii,"_"))#
</nobr>
<br>
</cfloop>
</form>
</td>

<td align="left">
<cfloop list="#payList#" index="ii">
<div id="#ii#" style="display:<cfif variables.billing_info is ii>inline<cfelse>none</cfif>;">
this is the <b>#ii# payment method</b><br>

cfinvoke component="???" method="getPayFields">
      cfinvokeargument name="payType" value="#ii#"
/cfinvoke

Can you please add to your example by showing me an instance of the different form fields that show up when the radios button are selected. I will not be using the component example I need to keep this as simple as possible.

<cfloop list="#payList#" index="ii">
<nobr>
<cfinput name="billing_info" id="billing_info" type="radio" value="#ii#" onclick="doPay(billing_info)" checked="no" required="yes"/>
#ucase(listlast(ii,"_"))#</nobr>
<br>
</cfloop></td>
    </tr>
  </table>
<div id="pay_check" style="display:<cfif variables.billing_info is pay_check>inline<cfelse>none</cfif>;">
