How to replace action/triggers with set variables

[kvr9]

Hi ,

I have a concern on creating a set variable for below conditions.

1.Currently I'm using a action button to select few countries.

Text object-action-set field-Country -search(List of Countries)

It works fine but the list of countries might change so taught of using a set varaiable in place of set field.

I tired in below way

set vcountrylist -'(A,B,C,D)'

SET vCountry == if(len(vcountrylist)> 0,vcountrylist,0);

Could someone help me on this.

Thanks In advance
