Assuming the database name of the ServiceType field is "u_servicetype", this should work: var gr = new GlideRecord('sys_user');
gr.get(g_user.userID);
var svcType = gr.u_serviceType;

var gr = new GlideRecord('sys_user');
gr.addQuery('sys_id',g_user.userID);
gr.query(function(user){
if(user.u_servicetype=="CMS"){
   return;
} else {
   // all the rest of your code...
}
});
