CakePHP - Undefined variable in view when using $this->set("variableName', $variable) in controller;

I'm trying to set a variable in the view for my controller as so:

This is Users/add action

public function add() { 
if ($this->request->is('post')) {
        $usertype = $this->User->Usertypes->find('list', array('fields' => array('id', 'description')));
        $this->set('usertype', $usertype);
        $this->User->create();
        if ($this->User->save($this->request->data)) {
            $this->Session->setFlash(__('The user has been saved.'));
            return $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The user could not be saved. Please, try again.'));
        }
    }
}

When using Debugger::dump($usertype); I get this

array(  (int) 1 => 'Staff',     (int) 2 => 'Administrator',     (int) 3 => 'Coordinator' )

So $usertype is definitely set correctly. In my view found at /View/Users/add.ctp I attempt to access to variable like so:

This is View/Users/add.ctp

<div class="users form">
<?php echo $this->Form->create('User'); ?>
    <fieldset>
        <legend><?php echo __('Add User'); ?></legend>
    <?php
        echo $this->Form->input('firstName');
        echo $this->Form->input('lastName');
        echo $this->Form->input('email');
        echo $this->Form->input('password');
        echo $this->Form->input('usertypes_id',array('options'=>$usertype));
    ?>
    </fieldset>
<?php echo $this->Form->end(__('Submit')); ?>
</div>

However I get an error "Undefined variable: usertype [APP/View/Users/add.ctp, line 10]"

I'm relatively new to CakePHP, I am doing something wrong here?

you are setting variable $usertype inside if, it means when request is POST but when you hit url request type is by default is GET.

you have to set your variable outside the if (before or after) otherwise the variable is set, bu then you are redirected to another page
