PayPal Error: the total of items in the cart did not match the total of all items

I have this issue with the cart I am currently completing, the price of each item is made of of several components some of which are flat rate and some of which are a cost multiplied by the qty ordered, the following code is the result of an order which includes an extra which is 20 cents x the qty i.e. $6 which as you can see is the difference between the total of the paymentdetailsitem and itemtotal

<paymentdetails>
 <ordertotal currencyid="USD">149.36</ordertotal>
 <shippingtotal currencyid="USD">98.36</shippingtotal>
 <itemtotal currencyid="USD">51</itemtotal>
 <buttonsource>WebAssist.eCartPHP.Pro.DP</buttonsource>
  <paymentdetailsitem>
   <name>SW-00033</name>
   <amount currencyid="USD">1.5</amount>
   <quantity>30</quantity>
   <number>10033</number>
  </paymentdetailsitem>
</paymentdetails>

my question is would I be better passing the line total and hard coding the qty to one in this code block

while ( !$eCart1->EOF() )      {
  $nextIndex = count($PP_DirectPayment_itemized[0]);
  $PP_DirectPayment_itemized[0][$nextIndex] = "Amount" . strval($cartIndex+1) . "";
  $PP_DirectPayment_itemized[1][$nextIndex] = "".$eCart1->DisplayInfo("Price")  ."";
  $nextIndex = count($PP_DirectPayment_itemized[0]);
  $PP_DirectPayment_itemized[0][$nextIndex] = "Name" . strval($cartIndex+1) . "";
  $PP_DirectPayment_itemized[1][$nextIndex] = "".$eCart1->DisplayInfo("Name")  ."";
  $nextIndex = count($PP_DirectPayment_itemized[0]);
  $PP_DirectPayment_itemized[0][$nextIndex] = "Number" . strval($cartIndex+1) . "";
  $PP_DirectPayment_itemized[1][$nextIndex] = "".$eCart1->DisplayInfo("ID")  ."";
  $nextIndex = count($PP_DirectPayment_itemized[0]);
  $PP_DirectPayment_itemized[0][$nextIndex] = "Quantity" . strval($cartIndex+1) . "";
  $PP_DirectPayment_itemized[1][$nextIndex] = "".$eCart1->DisplayInfo("Quantity")  ."";

    $eCart1->MoveNext();
    $cartIndex ++;
  }

or is there a better way to do this, maybe create a new column with a custom calculation to fill it ?

Thanks.

this depends on how you are managing the price.

Are you setting the item price using a calculation?

Normally, I would create a calculation named realPrice to calculate the price total

then modify the TotalPrice calculation. in the total price calculation, replace:
[Price]

with:
(realPrice calculation code)

then in the code that paces the item price to paypal:

$PP_DirectPayment_itemized[1][$nextIndex] = "".$eCart1->DisplayInfo("Price") ."";

use the realPrice instead:
$PP_DirectPayment_itemized[1][$nextIndex] = "".$eCart1->DisplayInfo("realPrice") ."";
