Select "Sum Price & Value" from the tools menu to get the total Price Paid, and total value of all items in the current view.

"Current View" includes all items currently viewable in the grid after any filters have been applied.

If no filter is applied, "Sum Price & Value" will give you total price paid and total value for all items in your collection.

If (for instance) you want to see the total price and value for all Lionel items, just set the filter screen to Company = Lionel, then click "Sum Price & Value."

The Item counter above will show the number of items included in each sum.
