Hi!

I have a little problem with a advance PDF/HTML form...

I have an impression template for a quote like this;
[ATTACH=JSON]{"data-align":"center","data-size":"custom","height":"424","title":"Captura de pantalla 2017-06-08 16.44.09.png","width":"447","data-attachmentid":423994}[/ATTACH]


What I need is that the items that are the same sum and throw a single item with the measure of the sum of all items, for this case should give;

EBONY CRYSTAL CEP x2                                     26.67                 M2                  $1,197.00               $31,923.99                $5,107.84
NERO DAVOLA FLAM.CEP 120x60x1.5                130                    M2                  $627.00                  $81,510.00                $13,041.60


Does anyone know what is the correct way to assign the function and condition for this to happen?
