Hi all,

I am fairly well versed in Cf but by no means an expert.

I am writing an App that requires user registration / payment. I have 5 steps:
1. Choose Member Type
2. Create Account
3. Payment
4. Receipt
5. Member CP

Currently I use #step# as my counter. (have tried both session.step and
cookie.step)

Basically  

<cfform action="register.cfm">
+ Hidden inputs to pass vars

register.cfm

<cfif IsDefined('form.step')>
       <cfswitch expression="#session.step#">
            <cfcase value="step_1">
            <cfset template = "/register/step_1.cfm">
       </cfcase>
            <cfcase value="v_step_1">
            <cfset template = "/register/v_step_1.cfm">
       </cfcase>

.....

I am using <cflocation> after each step is validated (v_) to prevent browser
refresh and duplicate DB entries.
I am running into difficulties with using session.step and cookie.step

session.step = No expiry and therfore going back creates a problem as the
<cfswitch moves the user automatically back to where they left off. (I also use
sessions to track user login)

cookie.step = not updating before the <cflocation and thus the same step is
repeated over and over

I would like to avoid using url.step

Looking for some suggestions / help / other way of doing it

Cheers
