My test case works great, using your code.
Names Default To Here( 1 );
dt = New Table( "Example",
Add Rows( 10 ),
New Column( "Comment",
Character,
"Nominal",
Set Values(
{"not blank", "not blank", "", "not blank", "", "not blank", "not blank",
"", "not blank", "not blank"}
),
Set Display Width( 89 )
),
New Column( "Excluded Sum",
Numeric,
"Continuous",
Format( "Best", 12 ),
Set Values( [5, 1, 51, 44, 6, 0, 7, 1.5, 9, -5] )
)
);
dt << Clear Row States();
dt << select where( :comment == "" | :Excluded Sum < 2 );
dt << invert row selection;
dt << exclude;
dt << hide;
