The purchase index is reached by signing in on your local copy as org_Admin1@example.com, then clicking on Purchases, then All Purchases in the left-hand menu There is a dollar amount in the totals, but it is the amount spent, We want to also have the Full Market Value total (the column to the right of the amount spent)
