Showing totals in text box based on selected variables

Hi,

I am trying to display totals in text box on application startup. I have tried following script but none of them work:

1.

TEXT_5.setText(DS_1.getDataAsString("NETVALUE",{"DC":DS_1.getVariableValueExt("VAR_DC")}));

2.

TEXT_5.setText(DS_1.getTotalsDisplay("DC"));

With 1 it is throws an error saying no match found for DC = 11. This is wrong as DS_1 displays the data for that variable

With 2 it displays the word "SHOW" but no total.

Thanks in advance.
