Hi @Jude8 

please try the below code and make modifications to your requirement

you can pass this ref qual in second variable

javascript: new scriptincludeName().YourFunctionName(current.variables.variable_a);

Script include:

 YourFunctionName: function(service) {  // service is your first selected variable-a

        var filterStr = '';

        var gr = new GlideRecord("your_table");

        gr.addQuery('field', service);

        gr.query();

        var pArray = [];

        while (gr.next()) {

            pArray.push(gr.fieldname.toString());

        }

        filterStr = 'sys_idIN' + pArray.toString();

        return filterStr;

    },
