Loop List using API Methods

Hi All,

My Bex Query Structure(With No KF'S) :

PRODUCTS ID         PRODUCTS NAME           Words1                 Words2

  1                            wax                                  asdsad                  wrffvbv

  2                            lighter                               sadadas                rgergbg

  3                            candle                              asdasds                wvvxdsd

In DS 1.3, i am stuck up in the below steps itself.

var arr_products = DS_1.getMembers("PRODUCTS", 30);   

var arr_words1 = DS_1.getMembers("Words1", 30);

var arr_words 2 = DS_1.getMembers("Words2", 30);

I got the values to get stored in array from above.

I am trying to achieve like below. Get the list in an array and loop over that array and concatenate the text values .

Expected Output like below in ListBox when selection of wax and lighter in product dimension filter :

wax
