Catalog Client Scripts: Get User Mobile Phone

[rmechols]

In our request catalog we auto populate "On behalf of" and their "location." The Get User Location client Script looks like this:

function onChange(control, oldValue, newValue, isLoading) {

if (newValue == '') {

return;

}

var obo = g_form.getValue('on_behalf_of').toString();

var user = new GlideRecord('sys_user');

user.addQuery('sys_id',obo);

user.query(callBack);

function callBack(user){

if(user.next()){

g_form.setValue('location',user.location);

}

}

//Type appropriate comment here, and begin script below

}

It works like a charm. I am running into issues adding the User's Phone number. I modified the Get User Location Script but I can't get it to populate the phone onChange:

function onChange(control, oldValue, newValue, isLoading) {

if (newValue == '') {

return;

}

var obo = g_form.getValue('on_behalf_of').toString();

var user = new GlideRecord('sys_user');

user.addQuery('sys_id',obo);

user.query(callBack);

function callBack(user){

if(user.next()){

g_form.setValue('phone',user.mobile_phone);

}

}

//Type appropriate comment here, and begin script below

}

What am I missing? 

Thank you
