Can someone please help me clean up these scripts?

[Hola Ola]

Hello,

I know that what I've written is a bunch of nonsense, but I am horrible at scripting and I would really like some help.

My goal is , once I type in a User (subject_person) to auto-populate my form field (appraisal_due_date) with the information that is on the HR Profile (u_appraisal_due_date). 

Pertinent Information:

Name of my Script Include: getUserHRProfileInformation

Name of HR Profile: sn_hr_core_profile

Name field on HR Profile: user

Here is the Nonsense the I have:

_____________________________________________________________________

Script Include: 

var getUserHRProfileInformation = Class.create();

getUserHRProfileInformation.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getUserHRProfileInformation: function() {

        var y = this.parameter('user');

        var gr = new GlideRecord('sn_hr_core_profile');

        gr.addQuery('sys_id', 'user');

        gr.query();

        if (gr.next()) {

            return gr.u_first_name + ';' + gr.u_last_name + ';' + gr.u_appraisal_due_date;

        }

    },

    type: 'getUserHRProfileInformation'

});

 __________________________________________________________________

CLIENT SCRIPT: On-change

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

    if (isLoading || newValue == '') {

        return;

    }

    //Type appropriate comment here, and begin script below

    var abc = g_form.getValue('subject_person');

    var ga = new GlideAjax('global.getUserHRProfileInformation');

    ga.addParam('sysparm_name', 'getUserHRProfileInformation');

    function pop(response) {

        g_form.setValue('appraisal_due_date');

        }

    }

Any help/assistance will be greatly appreciated.

Thank you

@Hola Ola My bad, I shared an incorrect client script earlier. Please try the following and see if it works.

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    //Type appropriate comment here, and begin script below
    var abc = g_form.getValue('subject_person');
    var ga = new GlideAjax('sn_hr_core.getUserHRProfileInformation');
    ga.addParam('sysparm_name', 'getUserHRProfileInformation');
    ga.addParam('sysparm_user, abc);
    ga.getXMLAnswer(getResponse)
    function getResponse(response) {
        g_form.setValue('appraisal_due_date',response);
        }
    }

@Hola Ola Please try the following version.

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    //Type appropriate comment here, and begin script below
    var abc = g_form.getValue('subject_person');
    var ga = new GlideAjax('sn_hr_core.getUserHRProfileInformation');
    ga.addParam('sysparm_name', 'getUserHRProfileInformation');
    ga.addParam('sysparm_user', abc);
    ga.getXMLAnswer(getResponse);

    function getResponse(response) {
        g_form.setValue('appraisal_due_date', response);
    }
}
