Seeing the SUM of more than 100 rows with a search applied

Seeing the SUM of more than 100 rows with a search applied

I have a table with approximately 650 rows. I need to apply search criteria, which limits the number of rows to 198. Then, while the search criteria is applied, I need to see the SUMs for several columns. When I click to go to the last record, it clears my search criteria and displays the SUM for all 650 rows. Am I doing something wrong, or missing something obvious?
