JSON code returning unwanted curly braces

[#1]

Hi, I am hoping to get returned numbers only, though am getting results like: - 

   {1.6853394618}

Can anyone help re-write this: -

{1.6853394618, 1.1953542099, 0.5582366613, 0.4790270411, 0.4159308661, 0.4145532579, 0.3847474328, 0.1964273334, 0.1680691329, 0.1715601671,
0.2542918024, 0.1972811076, 0.2371273713}[Loc Sorted( [3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15], :Age )]

You will have to add additional index at the end of your return value [1] (or use other method of getting the value from the list which is returned). This is because you are using matrix as the index -> return value will also be matrix (or in this case a list)

Loc Sorted( [3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15], :Age )

You could also make the above part of your script to return only single value instead of matrix

Thank you Jarmo.  I have tried your suggestions, though no success as I am likely mis-interpretating them (I am a beginner at this).  Could you give the entire code?

This hopefully gives the idea what I mean

Names Default To Here(1);

dt = Open("$SAMPLE_DATA/Big Class.jmp");
Row() = 1; 

my_list = {1.6853394618, 1.1953542099, 0.5582366613, 0.4790270411, 0.4159308661, 0.4145532579,
0.3847474328, 0.1964273334, 0.1680691329, 0.1715601671, 0.2542918024, 0.1972811076, 0.2371273713
};

m = my_list[Loc Sorted([3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15], :Age)];
val = my_list[Loc Sorted([3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15], :Age)][1];
val2 = my_list[Loc Sorted([3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15], :Age)[1]];

Show(m, val, val2);

Just re-starting @jthi 's suggestion in a single line, if you know you are are only going to ask for a single value, you can just add [1] to the end of your line, like this:

{1.6853394618, 1.1953542099, 0.5582366613, 0.4790270411, 0.4159308661, 0.4145532579, 0.3847474328, 0.1964273334, 0.1680691329, 0.1715601671,
0.2542918024, 0.1972811076, 0.2371273713}[Loc Sorted( [3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15], :Age )][1];
