HI Sidarth...

i am using global.AbstractAjaxProcessor   then also its giving same error...

can you please help me in this..

my script include..

var counttest = Class.create();

counttest.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {

      counttest: function() {

              vgs.log ('AAAA:This script is executing');

              var gr = new GlideRecord('incident');

              gr.query();

              if(gr.next())

                      { //Added this one

              var datedif = gs.dateDiff(gr.sys_created_on,gs.nowDateTime(), false);

              gs.log('AAAA:'+datedif);

              return datedif;

      }

},

type: 'counttest'

});

I tried the same thing in my instance and I did not get any error.

Can you let me know if you are using this in an application scope and whether client callable is selected?

hey Sidarth ..

My application scope is global ..... and yes i have checked client callable check box ...

and i am also not getting any error   but the output i am getting is NULL
