hot to print total amount of all donations [solved]

solved by myself thanks this formula into the LM_PayPal block:

<?php
if (function_exists('lm_paypal_donate')) {
$result = db_query("SELECT SUM(mc_gross) as total FROM lm_paypal_donations");
$pp = db_fetch_object($result);
print 'SnowPedia è un progetto open-source e no-profit. Ogni contributo è re-investito nel progetto. <a href="../../../lm_paypal/donations">Bilancio ';
print sprintf( "%01.2f", $pp->total+0 );
print '</a>'.lm_paypal_donate(array(10,20,array(30),50,100,200), 'EUR', 'donazione a SnowPedia', '', '');
}
?>
