how to get the slope/intercept values of orthogonal regression from a Bivariate Fit Chart in JSL?

In the following JSL script, I tried to get the values of slope and intercept of the orthogonal regression directly from the Bivariate Fit chart, but it always gives me error :-(... Any hint here?

biv = dt << Bivariate( Y( :New ), X( :Ref ), Fit Orthogonal( 1 ) );

rbiv = biv << Report;

slopebox = rbiv[Outline Box( 1 ),If Box(3), Outline Box(3),Table Box( 4 ), Number Col Box( 12 )];

slope = slopebox<< get(1);

This should work

names default to here(1);
dt = current data table();
biv = dt << Bivariate( Y( :New ), X( :Ref ), Fit Orthogonal( 1 ) );

rbiv = biv << Report;

slopebox = rbiv["Orthogonal Fit Ratio=1.000",NumberColBox( "Slope" )];

slope = (slopebox << get)[1];

P.S. In the future, when you enter JSL into a Discussion item, please use the JSL icon at the top of the entry window. It makes for a far more readable entry.
