How does JSL extract a subset of selected rows for a column in a data table?

[#1]

It seemed like a simple question, but I didn't succeed.
This selected line number is already selected by other scripts.

Thanks!

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

r = dt << Get Selected Rows();
d3 = dt << Subset( Output Table( "tt" ), Selected Rows( r ), selected columns( 0 ) );

selected rows() expects a boolean value, either 0 or 1.  In your example you would specify

selected rows( 1 )

which indicates to the platform to use selected rows for the subset.

Thank Jim!

d3 = dt << Subset(
	Output Table( "tt" ),
	Selected Rows( 0 ),
	Rows( dt << Get Selected Rows() ),
	Selected columns only( 0 )
);
