Drupal Help!

Hi, im trying to alter the default user registration form in Drupal but i can’t seem to get it.

Below is the function used to alter the form and i want to assign extra variables to it

function my_hook_form_user_register_alter(&$form, $sh_help, $sh_title) {
$form['user_registration_help']['#value'] = t($sh_help);

it is called by:

print drupal_get_form('user_register', $fields['help']->content, $fields['title']->content);

but it keeps on displaying:

warning: Missing argument 3 for my_hook_form_user_register_alter() …

What’s wrong? Can anybody here help?

I think you are going to have to consult the Drupal site. Generally though you are not conforming to the function signature you are calling.
