I'm in the beginning stages of learning BPMN, so any advice regarding the following would be very helpful!

We have an online payment process where the user clicks a link to begin the payment process.  After the link is clicked, I get their payment options (minimum amount due and payoff amount, specifically) and deliver them to the user.  This essentially ends one process that is part of the entire payment process.  Following is how I modeled this.

The above model illustrates how the user can get their payment options.  When a payment amount is selected it, along with basic account information, is sent to a third party payment company; thus another process has begun.  Following is how I've begun modeling this, and I'm not comfortable at all with how it's turned out.

I'm having a difficult time trying to get the "Get Payment Options" submodel to fit into the entire scheme of things.  When that first process ends, I can't figure out how to connect it to the rest of the payment process.

Any help would be GREATLY appreciated...
