You are using method=get in the form tag and trying to retrieve from the
$_POST variable. Either change the method to post or the variable to
$_GET

Thank you guys, i have solved the problem by changing [name="idschema"] and
by substituing <option value="opzione1"> with only <option>.
Now i'm able to select a value from the dropdown list menu and to deliver
it across the page. :-)
Thank you and have a nice day!
Matt.
