How to extract a numberical value from "Distribution" display box?

Hi, all

I met a problem in extracing a numeric value from a display box object.
It is very tricky and could not figure it out.
I have following table "Data.jmp", and try to fit its distribution using following JSL code:

dt = CurrentDataTable();
div = Distribution( Stack( 1 ),
Continuous Distribution(Column( :Value ), Horizontal Layout( 1 ), Vertical( 0 ),
Fit Distribution( Normal(Goodness of Fit( 1 ))), More Moments(1) ),
SendToReport( Dispatch( {"Value"}, "Distrib Outlier Box", FrameBox, Marker Drawing Mode( "Fast" )) )
);
r = div << Report;
skewness = r["Value"]["Moments"][NumberColBox(2)] << get(10);

But the code cannot run, because the error message: "Can't subscript Display Box in access or evaluation of 'Subscript' , r["Value"]["Moments"][Number Col Box( 2 )]"

Would you please advise me how to refer to the "Skewness" value in this display window?

Appreciate your kind help and effort.
Fred

Your script got mangled, but I could get the skewness by replacing the last line with:

skewness = r["Moments"][NumberColBox(1)][10];
