jQuery Grid Plugin - jqGrid

Hello. Great job here.
I'm sorry about my English
I'm starting to use jqGrid within a project and I'm having

some problems.
1. When I try to add the 'custom edit' column ,

only appear the title, there is no buttons. This make the

data columns move one step to left.

“Acciones” column should list the 'E', 'S', 'C' buttons,

like example here http://trirand.com/jqgrid/jqgrid.html,

but it don't do it.

2. It look like font does not read theme style.

this is my code:

HTML

….

<link rel=”stylesheet” type=”text/css” media=”screen” href=”images/themes/sand/grid.css” />

<script type=”text/javascript”

src=”javascript/jquery-1.2.6.js”></script>

<script type=”text/javascript”

src=”javascript/jqGrid/jquery.jqGrid.js”></script>
<script type=”text/javascript”

src=”javascript/jqModal.js”></script>
<script type=”text/javascript”

src=”javascript/jqGrid/js/jqDnR.js”></script>

….

<table id=”list” class=”scroll”></table>
<div id=”pager” class=”scroll” style=”text-align:center;”></div>

….

JS

jQuery(document).ready(function(){
  jQuery(”#list”).jqGrid({
    url:'services/service_bckusuarios.php',
    datatype: 'xml',
    mtype: 'POST',
    colNames:['Acciones','Nombre Completo',

'Nombre de Usuario', 'E-mail','Ultimo Ingreso'],
    colModel :[
      {name:'actions', index:'actions',align:'left',sortable:false},
      {name:'fullname', index:'fullname',align:'center',

editable:true},
      {name:'username', index:'username',align:'center',

editable:true},
      {name:'email', index:'email',align:'center',editable:true},
      {name:'lastlog', index:'lastlog',align:'center',editable:false}],
    pager: jQuery('#pager'),
    rowNum:1,
    rowList:[1,2,3],
    sortname: 'nombre_completo',
    sortorder: “asc”,
    viewrecords: true,
    imgpath: 'images/themes/sand/images',
    caption: 'Usuarios de backend',
    recordtext:'Usuarios en total',
    loadui:'block',
    loadComplete: function(){
        var ids = jQuery(”#list”).getDataIDs();
        for(var i=0;i<ids.length;i++){
             var cl = ids[i];
             be = “<input style='height:22px;width:20px;'

type='button' value='E'

onclick=jQuery('#list').editRow(”+cl+”); ></ids>”;
             se = “<input style='height:22px;width:20px;'

type='button' value='S'

onclick=jQuery('#list').saveRow(”+cl+”); />”;
             ce = “<input style='height:22px;width:20px;'

type='button' value='C'

onclick=jQuery('#list').restoreRow(”+cl+”); />”;
             jQuery(”#list”).setRowData(ids[i],{act:be+se+ce})
        }
    },
    editurl: 'services/service_bckusuarios.php'
             
  }).navGrid('#pager',{refresh: true, edit: false, add: true, del: false, search: true});
});

Please give me a hand.

Thank you very much.
