vBulletin 4 Request - Error with functions_login.php

[Alice]

So, I'm trying to add new code to the function_login.php file. I'm using v4.2.5. The following is that I added after the verify_authentication section, which is:

// ###################### Start verify_gameAuth #######################
function verify_gameAuth($username, $password, $md5password, $md5password_utf, $cookieuser, $send_cookies)
{
	global $vbulletin;

	$username = strip_blank_ascii($username, ' ');
	// See VBM-635: &#xxx; should be converted to windows-1252 extended char. This may not happen if a browser submits the form. But from API or user manually input, it does.
	// See also vB_DataManager_User::verify_username()
	$charset = strtolower(vB_Template_Runtime::fetchStyleVar('charset')) == 'iso-8859-1' ? 'windows-1252' : vB_Template_Runtime::fetchStyleVar('charset');	
	$callback = new Convert_unicode_char_to_charset_callback($charset);
	$username = preg_replace_callback(
		'/&#([0-9]+);/i',
		array($callback, 'callback'),
		$username
	);

	if ($vbulletin->userinfo = $vbulletin->db->query_first("SELECT userid, usergroupid, membergroupids, joindate, infractiongroupids, username, password, salt FROM " . TABLE_PREFIX . "user WHERE username = '" . $vbulletin->db->escape_string(htmlspecialchars_uni($username)) . "'"))
	{
		if (
			$vbulletin->userinfo['password'] != iif($password AND !$md5password, md5(md5($password) . $vbulletin->userinfo['salt']), '') AND
			$vbulletin->userinfo['password'] != iif($md5password, md5($md5password . $vbulletin->userinfo['salt']), '') AND
			$vbulletin->userinfo['password'] != iif($md5password_utf, md5($md5password_utf . $vbulletin->userinfo['salt']), '')
		)
		{
			$return_value = false;
			($hook = vBulletinHook::fetch_hook('login_verify_failure_password')) ? eval($hook) : false;
			if (isset($return_value))
			{
				// unset $return_value if you want to run the $send_cookies stuff
				return $return_value;
			}
		}
		else if ($vbulletin->userinfo['password'] == '')
		{
			// sanity check, though there should never really be an empty string for a password
			$return_value = false;
			($hook = vBulletinHook::fetch_hook('login_verify_failure_password')) ? eval($hook) : false;
			if (isset($return_value))
			{
				// unset $return_value if you want to run the $send_cookies stuff
				return $return_value;
			
		}

		if ($send_cookies)
		{
			set_authentication_cookies($cookieuser);
		}
		
		$return_value = true;
		($hook = vBulletinHook::fetch_hook('login_verify_success')) ? eval($hook) : false;
		return $return_value;
	}

	$return_value = false;
	($hook = vBulletinHook::fetch_hook('login_verify_failure_username')) ? eval($hook) : false;
	return $return_value;
}

After I save and upload the file, I get the following error, which is:

Parse error: syntax error, unexpected end of file in /home/swghopec/public_html/forums/includes/functions_login.php on line 612

Any help that can be provided, I would really appreciate it.

Thank you,
