I solved problems 1 and 2 but now I have problem 3: I see only one result even though I should see 2 in case user selects just Devon.

Search page:
Code:
<?
// If submitted, check the value of "select". If its not blank value, get the value and put it into $select.
if(isset($select)&&$select!=""){
$select=$_GET['select'];
}
?>

<form id="sel_city"
...
