This fixed my problem for getting the order detail to return.
Now, if someone could give me a pointer on how to change the Payment method from saying, "Payment Method: MODULE_PAYMENT_PAYPAL_IPN_TEXT_T" I'd be extremely grateful. I can probably figure it out messing with it, but a quick answer would save me time tomorrow night.
