Order info not sent to merchant after PayPal payment

My client is getting a partial email after PayPal processes the order. She's getting the subtotal, shipping and total figures as well as the billing info, but the order details are not included. I've tried to locate the email doc that's sent to bind in additional details, but can't figure out which it is. What file should I look for and how do I proceed?

Okay, I think I found it in the webassist/email folder. I have muirhead_receipt.php but also muirhead_receipt 2.php and muirhead_receipt2.php, all with the same date. How do I tell which one is being used?

I've attached muirhead_receipt2.php which I think is the most likely.

And another issue... I just noticed that while it is including my "West of Mississippi" added charge in the total, it's not breaking it out on the cart. I can see where I would add that PHP statement on the checkout page, below Shipping and before Tax, but not sure of the syntax. Here's the rule from the eCart page (muirhead_PHP.php):

//eCart Rule
function WAEC_muirhead_WestoftheMississippi()  {
  $totalShipping = 0;
  if (true && (((isset($_SESSION['toTheWest'])?$_SESSION['toTheWest']:"") == "1"))) {
    $totalShipping += floatVal("3.50");//Result
  }
  return WA_eCart_FormatNumber($totalShipping, $this->ForceDecimalsC, $this->DecimalPlacesC);
}
//eCart Rule
