Drupal 7 Hook_forms not working - drupal

Question

Can anyone tell me why this is not working?
The drupal_render(drupal_get_form) is dynamically created in a foreach loop and put into a table theme.
Everything loads except the form fields. I've tried debugging by adding echos and exits to each form function call, but the page continues to load. I am not sure if these functions are simply not being called or if there is some other issue.
foreach( $w as $k => $v ) {
$r[] = array(
'$'.number_format($v->amount, 2),
date('F d, Y', $v->created),
filter_xss($v->paypal_email),
drupal_render(drupal_get_form(('toefl_tutors_admin_withdrawl_request_form_'.$v->id), $v->id))
);
}
function toefl_tutors_admin_withdrawl_request_forms($form_id, $args) {
$forms = array();
if (!empty($args) && $form_id == 'toefl_tutors_admin_withdrawl_request_form_' . $args[0]) {
$forms[$form_id] = array(
'callback' => 'toefl_tutors_admin_withdrawl_request_form',
'callback arguments' => array($args[0]),
);
}
return $forms;
}
function toefl_tutors_admin_withdrawl_request_form($form, &$form_state, $id = 0) {
$form['twid'] = array(
'#type' => 'hidden',
'#value' => $id
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Send Money'),
'#attributes' => array('class' => array('btn', 'btn-success'))
);
return $form;
}

Answer 1

I've solved the problem.
I needed to rename the hook_forms function to toefl_tutors_forms() because My module name is actually toefl_tutors not toefl_tutors_admin_withdrawl_request
Apparently and correct me if I am wrong, in order to use hook_forms you must name it mymodulename_forms, not mymodulename_xx_forms.
What confused me was hook_form works perfectly when you name the form function mymodulename_xx_form().
