PayPal IPN listener does not work when adding trial period to a subscription

Question

I have a subscription based streaming site in which I am trying to implement a trial period of 3 days prior to the user being charged the monthly fee.

THINGS TO KNOW

It works fine before implementing the trial code on the payment page (IE: a user is charged and their subscription automatically begins. Paypal IPN shows response)
I'm pretty sure I need to add variables to the listener but this is where I am having issues.
Providing below the unmodified payment code, unmodified listener code, paypal ipn response from unmodified code, modified payment code, and ipn response when using modified payment code
Some of the info in the code provided has REMOVED to protect information
