Show in the central warehouse on the part of the total value under the regular price column the total sum of all prices of goods in the warehouse. Summed up so that it counts not by items of goods but by their quantity, for example, there are goods A - 30 pieces of $ 10 and goods B - 15 pieces of $ 5, in general there are 2 types of goods (A and B) A - 30 pieces of $ 10 is $ 300 and B - 15 pieces of $ 5 is 75$ so let it display on the table row of the central warehouse the total values under the column regular price - the sum of all prices of goods that is (300$+75$) 375$.
