//Type appropriate comment here, and begin script below

var count = 0;

var mrvsData = g_form.getValue("abcd"); //replace with mrvs internal name

var mrvsDatastr = JSON.parse(mrvsData);

for (var i = 0; i < mrvsDatastr.length; i++) {

count = count + parseInt(mrvsDatastr[i].amt); //map your variable names

Hi @Suraj_18_18 ,

did add the onSubmit client script on the variable set?

if yes

add it on the catalog item instead of MVRS

Please mark my answer as helpful/correct if it resolves your query.

HI @Suraj_18_18 ,

inside mvrs you can only access variables in the mvrs using client script 

to access variables outside mvrs you have to use g_service_catalog api

g_service_catalog.parent.getValue("variable/MVRS internal name")

there is no way to set the value of a variable outside MVRS 

you have to keep the onsubmit client script on the record producer itself instead of MVRS

Please mark my answer as helpful/correct if it resolves your query.
