Sembra funzioni con le ultime modifiche.
Grazie per l'aiuto.
Ho eliminato il terzo file elimina.php e rifatto il secondo file trova.php come segue :

<?php
$elimina = $_POST['Tipox'];
$num = $_GET['id'];
$nome_file_inc = "include/altopaginefreeplus.php";
if (file_exists("../".$nome_file_inc)) {
include_once ("../".$nome_file_inc);
}
else {
if (file_exists($nome_file_inc)) {
include_once ($nome_file_inc);
}
}
$nome_file_inc = "include/accessodatabase.php";
if (file_exists("../".$nome_file_inc)) {
include_once ("../".$nome_file_inc);
}
else {
if (file_exists($nome_file_inc)) {
include_once ($nome_file_inc);
}
}
$sql = 'SELECT tabella.NOME,tabella.NUM FROM tabella WHERE trim(tabella.NUM)="'.$elimina.'"';
$result = mysql_query($sql, $global_db);
$nresult=0;
while ($ris = mysql_fetch_array($result)) {
$res[$nresult]["NOME"] = $ris["NOME"];
$res[$nresult]["NUM"] = trim ($ris["NUM"]);
if ($res[$nresult]["NUM"]) {
$nresult++;
}
}
