<?

if($user->uid)

{
if (module_exists('userpoints')) { $points = array( 'uid' => $user->uid, 'points' => 5, 'description' => 'For inviting people!', 'event' => 'invite', 'tid' => 34, 'moderate' => false);
}
}

$a=$form_values['submitted_tree']['email1'];
$b=$form_values['submitted_tree']['email2'];
$c=$form_values['submitted_tree']['email3'];
$d=$form_values['submitted_tree']['email4'];
$e=$form_values['submitted_tree']['email5'];

$firstname=$form_values['submitted_tree']['firstname'];

$firstnamea=$form_values['submitted_tree']['firstname1'];
$firstnameb=$form_values['submitted_tree']['firstname2'];
$firstnamec=$form_values['submitted_tree']['firstname3'];
$firstnamed=$form_values['submitted_tree']['firstname4'];

$msg=$form_values['submitted_tree']['textarea_message'];

$bodyheadera="Dear ".$firstnamea.":"."\n".$firstname." invited you to join MyGivingPoint!"."\n"."\n";

$bodyheaderb="Dear ".$firstnameb.":"."\n".$firstname." invited you to join MyGivingPoint!"."\n"."\n";
if($msg!="")
{
$body=$firstname." says:'".$msg."'"."!"."\n"."\n";
}
$body=$body."Mygivingpoint.org is a website designed for young people ages 13 - 19 years. GivingPoint helps teens find their passion and connect to community activities that interest them most.

drupal_mail($mailkey, $b, $subject, $bodyb, $from, $headers=array())
