Hi Joel...
Your query should have one condition on lastname=param1... In your radio button code (each modification of the radio button), if you want to filter, then you do a query.paramName=gsLastName, if you don't want to filter you do query.paramName=NULL
Any parameter with a NULL value is ignored!
After that, you restart your query (hexecutequery) and redisplay your table content
