New Shipping Field information sent in email

Hello, I've added a new field to the shipping form using the hook mentioned in another post. Everything is working great, and I even have the value displaying on the order when the admin comes in and looks at it. However, I can't seem to find how to add it to the initial email that gets sent out to both the admin and the person who made the order. I can see in the files, as well as in the messaging tab, where "SHIPPINGINFO" gets replaced by the actual shipping information. But I can't find where that is actually being populated with the real shipping information so I can add my new field to it. Any help would be great, I'm so close on this :slight_smile:
