Display Total Value on a label

Hi All, I wanted to use total value on a lable for a key figure coming from data source. I had no idea how to get this as it was asking me to put something in 2nd argument. I did not want to put any break so i used these brackets and it worked. Not sure i knew or learnt form somewhere. Now if i want to filter data based on two values out of 5 values for a dimension ? how should i do it..

TEXT_4.setText(DS_1.getDataAsString("3HVXO0TBR33OO0NKRB9I6G850", {}));

something like this? It seems does not work,, only one value for a filter seems to be working,, Can i apss an array of values to one domension?

TEXT_4.setText(DS_1.getDataAsString("3HVXO0TBR33OO0NKRB9I6G850", {"Dimension":"1","2"}));
