CException Error

I am new to yii and installed V1.1.

I installed crud and register some users, but when click on manage user it goes to an error page.

The column must be specified in the format of "Name:Type:Label", where "Type" and "Label" are optional.

foreach($this->columns as $column)

401             $column->init();

402     }

403 

404     /**

405      * Creates a {@link CDataColumn} based on a shortcut column specification string.

406      * @param string $text the column specification string

407      * @return CDataColumn the column instance

408      */

409     protected function createDataColumn($text)

410     {

411         if(!preg_match('/^([\w\.]+)(<img src='http://www.yiiframework.com/forum/public/style_emoticons/default/sad.gif' class='bbc_emoticon' alt=':(' />\w*))?(<img src='http://www.yiiframework.com/forum/public/style_emoticons/default/sad.gif' class='bbc_emoticon' alt=':(' />.*))?$/',$text,$matches))

412             throw new CException(Yii::t('zii','The column must be specified in the format of "Name:Type:Label", where "Type" and "Label" are optional.'));

413         $column=new CDataColumn($this);

414         $column->name=$matches[1];

415         if(isset($matches[3]) && $matches[3]!=='')

416             $column->type=$matches[3];

417         if(isset($matches[5]))

418             $column->header=$matches[5];

419         return $column;

420     }

421 

422     /**

423      * Registers necessary client scripts.

424      */

My admin.php Code is:

<?php

/* @var $this UsersController */

/* @var $model Users */

$this->breadcrumbs=array(

'Users'=>array('index'),


'Manage',

);

$this->menu=array(

array('label'=>'List Users', 'url'=>array('index')),


array('label'=>'Create Users', 'url'=>array('create')),

);

Yii::app()->clientScript->registerScript(‘search’, "

$(’.search-button’).click(function(){

$('.search-form').toggle();


return false;

});

$(’.search-form form’).submit(function(){

$('#users-grid').yiiGridView('update', {


	data: $(this).serialize()


});


return false;

});

");

?>

<h1>Manage Users</h1>

<p>

You may optionally enter a comparison operator (<b>&lt;</b>, <b>&lt;=</b>, <b>&gt;</b>, <b>&gt;=</b>, <b>&lt;&gt;</b>

or <b>=</b>) at the beginning of each of your search values to specify how the comparison should be done.

</p>

<?php echo CHtml::link(‘Advanced Search’,’#’,array(‘class’=>‘search-button’)); ?>

<div class="search-form" style="display:none">

<?php $this->renderPartial(’_search’,array(

'model'=>$model,

)); ?>

</div><!-- search-form -->

<?php $this->widget(‘zii.widgets.grid.CGridView’, array(

'id'=>'users-grid',


'dataProvider'=>$model->search(),


'filter'=>$model,


'columns'=>array(


	'id',


	'username',


	'password',


	'‘email’',


	array(


		'class'=>'CButtonColumn',


	),


),

)); ?>
