Setting up payplans Plans to match up with their Easy Social profile workflow.

I have created 3 paypal plans and I have created 3 profiles.

When a person joins the Lost my Dog plan I want the registration form to choose the I lost my dog work flow and profile

when they join the I lost my cat, I want it to work with the I lost my cat work flow

And the third the same.

what am I doing wrong. I am testing this on another site I own before I switch my chambers from jomsocial to your software.

Thanks for your help.
