Hi Roberto,

Try below something as below, not tested but with should be aligned to this logic

template.print("Requested items: <br>");

var gr = new GlideRecord("sc_req_item");
gr.addQuery("request", current.sys_id);
gr.query();
while(gr.next()) {
    var stage = gr.stage.getDisplayValue();
    if (JSUtil.nil(stage))
        stage = gr.stage.getChoiceValue();
    template.print(gr.number + ": " + gr.cat_item.getDisplayValue() + ", Stage: " + stage + "<br>");
    
    // Retrieve and print variables for each requested item
    var variables = new GlideRecord('sc_item_option_mtom');
    variables.addQuery('request_item', gr.sys_id);
	    variables.orderBy("sc_item_option.order");
		variables.query();
    while(variables.next()) {
if(variables.sc_item_option.item_option_new.type=='8')//if reference field 
{
var question = variables.sc_item_option.item_option_new.getDisplayValue();
var answer = getDisplayNames(variables.sc_item_option.value.getDisplayValue());
template.print(question + ": " + answer + "<br>");
}
else
{
        var question = variables.sc_item_option.item_option_new.getDisplayValue();
        var answer = variables.sc_item_option.value.getDisplayValue();
        template.print(question + ": " + answer + "<br>");
    }

    template.print("<br>"); // Adds a space between items for better readability
}
}

function getDisplayNames(sysidofrecord)
{
var rec = new GlideRecord('sys_user'); 
 if(rec.get(sys_id)) {
return rec.getDisplayValue();
}
}
