Ok, so in the request it's sending an AMT of 135.00. The line item is for 270.00 and then it shows a discount of 108, so that would be 162.00, which is what it's sending for the ITEMAMT.
I can't see why it's only sending 135.00 for the total AMT, though. Typically, ITEMAMT + SHIPPINGAMT + TAXAMT + HANDLINGAMT = AMT. In this case, though, the shipping and tax are showing 0.00, yet somehow the full order total is getting dropped all the way to 135.00 when the item subtotal iself is 162.00.
Do you have any idea where it's losing that extra $27?
