using the script include to access the incident table

[instance]

In the Catalog items i have a field name incident (

using the script inlcude what i select in the incident field --> that particular caller_ID  should be seen in the callerid field.

but the caller_id of the incident is not coming. what is wrong with the script?

@Vishal Birajdar its working fine .

Update the Client Script As below :

Client Script :

On Change of Variable - 'incidents' 

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

var incidents = g_form.getValue('incidents'); 
var gaINCUsers = new GlideAjax('getUserUtils'); // Glide Ajax
gaINCUsers.addParam('sysparm_incidentSysIDs', incidents); // variable values passed to script include
gaINCUsers.addParam('sysparm_name', 'getCaller'); // function name in script include
gaINCUsers.getXMLAnswer(callback);

function callback(answer) {

var results = JSON.parse(answer);
var storeValues;
for(var int i ;i<results.length ; i++){
storeValues = storeValues + 'Incident= ' + results[i].incident + ' ' + 'Caller = ' + results[i].callerID
}
g_form.setValue('fields',storeValues);

}

}

@Vishal Birajdar  i have Tried But it is displaying undefined only

Script include :

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

getCaller: function() {
// Create Object to get Incident number and caller ID from incident
var users = [];

// get Incident sys Ids from client script
var incidentSysIDs = this.getParameter('sysparm_incidentSysIDs');

// glide record on incidnet table 
var grINC = new GlideRecord('incident');
grINC.addEncodedQuery('sys_idIN' + incidentSysIDs); //query with incident sys id
grINC.query();
while (grINC.next()) {
var info ={
incident: '',
callerID: '',
// if you have a called field on catalog form as reference then use sysId
sysId:'', 
};
//store values in users object
info.incident = grINC.getValue('number').toString();
info.callerID = grINC.getDisplayValue('caller_id').toString();
info.sysId = grINC.getValue('caller_id').toString();


users.push(info);
}

gs.log('getUserUtils:Information= ' + JSON.stringify(users));

return JSON.stringify(users);
},

Client Script :

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var incidents = g_form.getValue('incidents');
var gaINCUsers = new GlideAjax('getUserUtils'); // Glide Ajax
gaINCUsers.addParam('sysparm_incidentSysIDs', incidents); // variable values passed to script include
gaINCUsers.addParam('sysparm_name', 'getCaller'); // function name in script include
gaINCUsers.getXMLAnswer(callback);

function callback(answer) {

var results = JSON.parse(answer);
var storeValues =[];
for (var i = 0; i < results.length; i++) {

storeValues.push('Incident:' + results[i].incident + ' ' + 'Caller = ' + results[i].callerID );
}

g_form.setValue('fields', storeValues);
}

}

This will  definitely work.
