RMS - Inter-Store Transfers customizations.

I'm trying to modify the Inters-Store transfers print outs and ADD the regular price of the entries (not the cost) being transferred. Modifying the file POXfr.xml, I managed to display other information about the entry (like the sub-description 3 that we use here in our system), but I can't find the right "field" in the array for the price.  This is the part of my XML file displays the right info about the entries:

<FOR each = "PurchaseOrderEntry">           
   <ROW>PurchaseOrder.Entry.QuantityOrdered "|" PurchaseOrder.Entry.LookUpCode "|" PurchaseOrder.Entry.Description "|" PurchaseOrder.Entry.SubDescription3 </ROW>        
</FOR>

 Does anybody know how can I do this?
