I have followed all the steps a few times now (after having deleted any previously created reports/dashboards) yet cannot get past the Verify step as it keeps telling me that my report does not contain the 'Supply: Supply Name', 'Unit Cost', 'Quantity' and 'Total Cost' columns - yet this is all my report does contain. I have even tried adding and then removing other columns all to no avail. The report runs ok and the dashboard displays the output of the report ok so no idea why it gives the error
