Jimmy,
Filters and grids are not common :) Whenever possible do not use (personal opinion).
Instead try making Recordsource directly an SQL (needs index on name1 and name2). Then all you would do is a grid.refresh or grid.recordsource=grid.recordsource if not indexed (I don't know why but grid goes blank if not indexed).
