Can someone explain to me where is/are the mistake/s?

<script type="text/javascript">
$(document).ready(function () {
//Prepare jTable
$('#PeopleTableContainer').jtable({

pageSize: 50,
sorting: true,
defaultSorting: 'Name ASC',
actions: {
listAction: 'PersonActionsPagedSorted.php?action=list',
createAction: 'PersonActionsPagedSorted.php?action=create',
updateAction: 'PersonActionsPagedSorted.php?action=update',
deleteAction: 'PersonActionsPagedSorted.php?action=delete'
},
fields: {
PersonId: {
key: true,
create: false,
edit: false,
list: false,
width: '5%',
},
Fecha: {
title: 'Fecha',
width: '10%',
type: 'date',
}
Nombre: {
title: 'Nombre',
width: '10%',
options: { '1': 'Option1', '2': 'Option2', '3': 'Option3','4': 'Option4' }
