The table name is the problem, because listbox with RowSourceType=6 expects an alias, not a table name. So, you should make sure the table is open and know its alias. Since you already have the table names in the option buttons captions, you can make sure these tables are open, and store their aliases somewhere (maybe by adding a property to the buttons themselves). Whichever way you do this,

thisform.list1.rowsource=lcTheAlias+".lContact,fcontact"

And the rest will be OK then.
