Selezione dati da MySQL

[Thinker]

Ok, risolto, avevo sbagliato ad inserire il codice ^^"

L'ho adattato alle mie esigenze:

<?php
$result = mysql_query("SELECT * FROM `amicizie` WHERE user_id = '$viewprofile'");
$number = mysql_num_rows($result);
$row = mysql_fetch_array($result);

if($number > 0){
$i = 0;
while ($number > $i) {
$user_id = mysql_result($result,$i,"user_id");
$myfriend = mysql_result($result,$i,"friends");

$stringa.=$myfriend; 

$editname_result = mysql_query("SELECT * FROM utenti WHERE id = '$stringa'");
$editname_number = mysql_numrows($editname_result);

$editname_result_avatar = mysql_result($editname_result,$i,"immagine");
$editname_result_username = mysql_result($editname_result,$i,"nome");

print "<a href=\"***/profile/?id=$stringa\" /><img src=\"$editname_result_avatar\" alt=\"avatar\" />
$editname_result_username</a> ";

$i++;
}

$stringa=str_replace("[/id][id]","",$stringa); 
$stringa=str_replace("[id]","",$stringa); 
$stringa=str_replace("[/id]","",$stringa); 
echo $stringa; 
}
else{ echo"Nessun amico"; }
?>

Mi dà però questo errore:

Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 43 in ***/index.php on line 289

Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 43 in ***/index.php on line 290

Warning: mysql_result() [function.mysql-result]: Unable to jump to row 0 on MySQL result index 43 in ***/index.php on line 291 

le righe sarebbero

$editname_result_avatar = $editname_result_avatar = mysql_result($editname_result,$i,"immagine");
$editname_result_username = mysql_result($editname_result,$i,"nome");
