Inventory on hand value

I am trying to understand how Manager calculates the value of stock left after sales? It appears that when I click on the total on the summary pages it is deducting the cost value from the total. All I want is for it to give me a total value of what is left to sell not the value as it differs from my start date. Can anyone help?

when I say deducting the cost value I mean of the items already sold

Manager is using perpetual weighted average costing method to calculate cost of each sold item.

See: What inventory system is adopted by Manager?

What do you mean by wanting “total value of what is left to sell”? Inventory on hand asset account shows this.
