                                     'class'=>'js-validation-login form-horizontal push-30-t push-50',
                         )
                          ));
 // var_dump($model); exit;

// var_dump($_POST); exit;
 //$options = array ('12' => 'Twelve', '10' => 'Ten');
 echo $form->dropDownList('useraccountnumber','',array($model->attributes));



   $this->endWidget();

The error is related to the fact you don't you th $model and $accountNumber alternatively each to other. In this situation when you need/use $model your code don't have setted $accountNumber, conversely when you need/use $accountNumber your code don't have setted $model.

I Think you should rethink your logic. A solution could be render separated view (eg: moneyRequest, moneyByAccount ) each related to the correct variable ...
