You need something like

SELECT category, SUM(fee) FROM tblproducts WHERE category like 'Phorno
+';

That should be it. Since SUM is a grouping func, you need to apply all grouping rules to the selects you plan. Hence be sure the SUM set returns an unique index (for example the CATEGORY here, for which is made a subset).
Without the WHERE, I'd have as much rows in the resulting recordset as there are CATEGORIES in the table.

Hope I made myself clear. :)
