Filter Through Membership Subscription Plans


I'm building a site which has several subscription options which require filtering through a questionnaire to select the final subscription.

I've setup the links starting here.

If you follow the top option through to Step Four, this is where the three subscription levels are displayed. I'm trying to use shortcodes to embed the subscription plan details and functions into the accordion panels.

Is this possible? Is there a better way to filter through 20+ subscription plans to a simple list of subscriptions?

Thank you in advance!
