print_r($myarray[$contosotto]);

mi da:

Array
(
[0] => 4
[1] => 0.75
[2] => 7.5
[3] => 669.5
...
)

ma facendo

echo " <td>$myarray[$contosotto][1]</td>
<td>$myarray[$contosotto][3]</td>
<td>$myarray[$contosotto][8]</td>
<td>$myarray[$contosotto][10]</td>";

viene: <td>Array[1]</td>
<td>Array[3]</td>
<td>Array[8]</td>
<td>Array[10]</td>

come mai?
