Script Include returning null?

[Sid_Takali]

Hi all, 

The following Script returning null value. I need consumer sys_id. Thanks in advance 

Script Include - 

var customerPhones = Class.create();
customerPhones.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {

    ConsumerS: function() {
        var g = this.getParameter('syparm_cons');
        var CONsumer = '';
        gs.info("Include::::" + g);
        var gr1 = new GlideRecord('sn_customerservice_product_service_support');
        gr1.addQuery('sys_id', g);
        gr1.query();
        if (gr1.next()) {
            CONsumer = gr1.consumer;
        }
        return CONsumer;

 },

Client Script - 

        var ans = '';
        var con = g_form.getValue('parent');

        var ga1 = new GlideAjax('sn_customerservice.customerPhones');
        ga1.addParam('syparm_name', 'ConsumerS');
        ga1.addParam('syparm_cons', con);
        ga1.getXML(HelloWorld);

        function HelloWorld(response) {
            ans = response.responseXML.documentElement.getAttribute("answer");
            alert(ans);
        }

Hey Aman,

Yes, make sense.

@Siddharam if you need more field from that record then you can use getReference, if you need only one value then its better to go with GlideAjax.
