Here's how I'd do it:

$eElement=new Zend_Form_Element_Text('audience_total');
$eElement->setLabel('Audience Total');
$eElement->setRequired(true);
$eElement->setFilters(Array('Digits'));
$eElement->size(15);
$validator=new Zend_Validate_Digits();
$eElement->addValidator($validator,true);
$validator=new Zend_Validate_GreaterThan(1);
$eElement->addValidator($validator,true);
$this->addElement(true);
