Hello @lucky24 

Use this 

And for your reference use this link as well-

var mrvsRows = ritm.mrvs_name;
//The above will return a string in the form of array and objects. Now you will have to parse it
var oMrvs = JSON.parse(mrvsRows);
var desc;
for(var i in oMrvs) {
	desc += oMrvs[i]["cost_field_name"];
..... give every field name of variable set
}
ritm.description = desc;
