The program calculates the amount as Quantity * Unit Price (LCY). If  you change one of these fields, the entry in the Total Price (LCY) field  will be changed accordingly.
Program izračuna znesek takole: »Količina« * »Cena enote (LVT)«. Če spremenite vsebino katerega izmed polj, program skladno s tem spremeni postavko v polju »Skupna cena (LVT)«.
