Total Value in PO

Hi all,

I have created one PO. In PO 4 Line items are there. I have entered all the conditions ( Exice duty, freight, entry tax, insurance, P&F charges etc) for each line item. Now I would like to see the total price of Each line item and Total PO value. Actually in Net price field it is showing only the discount of gross.

How to know the total value for each PO item and Total PO value.
