I have a query ... that queries BIDDER NUMBER, ITEM NUMBER, HIGH BID and totals the High Bid Column
Your bidder query needs to have the bidder name field from the bidder table, and a text box on the report to show it. Probably you don't need the bidder number to show on the report, and if so, I'd simply make it invisible rather than delete it from the report. Removing it may cause issues.
Or are you asking how to create an expression in a text box that says "TOTAL OF ITEMS WON BY: JOHN DOE"?
The more we hear silence, the more we begin to think about our value in this universe.
