 Hi all, I have a requirement of get the MRVS values and set it into a Multiline text which is present inside a SingleRow Variable set from a catalog item but when it came to RITM and sc_task the vlaue is not visible accurately as expected.

i have attached the picture i have to set memebr of the distribution list  to the ITS CE-API API variable which is a multiline text set inside a single row variable set. i have write a OnSubmit() client script.but it is not giving accurate output it is show '/'  and the sys-id of the member i have tried

function onSubmit() {

    // Retrieve the value of the 'members_of_the_distribution_list' field

    var mvrsValue = g_form.getValue("members_of_the_distribution_list");

    g_form.setValue("api_variable", JSON.stringify(mvrsValue));

}

but it is not working can any one suggest how to achieve it through workflow
