Your search page defines the rsItems recordset three times in a row:
$query_rsitems = "SELECT UserAge,UserSex,UserTypes,UserArea,UserEthnicity FROM users GROUP BY UserSex";
$rsitems = mysql_query($query_rsitems, $localhost) or die(mysql_error());
$row_rsitems = mysql_fetch_assoc($rsitems);
$totalRows_rsitems = mysql_num_rows($rsitems);
$query_rsitems = "SELECT DISTINCT UserAge,UserSex,UserTypes,UserArea,UserEthnicity FROM users";
$rsitems = mysql_query($query_rsitems, $localhost) or die(mysql_error());
$row_rsitems = mysql_fetch_assoc($rsitems);
$totalRows_rsitems = mysql_num_rows($rsitems);
$query_rsitems = "SELECT DISTINCT UserAge, UserTypes, UserArea,UserSex FROM users";
$rsitems = mysql_query($query_rsitems, $localhost) or die(mysql_error());
$row_rsitems = mysql_fetch_assoc($rsitems);
$totalRows_rsitems = mysql_num_rows($rsitems);
PHP cpde is run from line 1 to the end, one line at a time, by the time you get to the code that creates the select list using the rsitems recordset, the last on is the one that is being used:
SELECT DISTINCT UserAge, UserTypes, UserArea,UserSex FROM users
Hers what you need to do:
Create a recordset fro each select list, one for the gender, one for the ethincity, one for the age etc....
rsGender:
SELECT DISTINCT UserSex FROM users
rsAge:
SELECT DISTINCT UserAge FROM users
rsType:
SELECT DISTINCT UserTypes FROM users
rsArea:
SELECT DISTINCT UserArea FROM users
rsEthnicity:
SELECT DISTINCT UserEthnicity FROM users
Each select list should use the recordset created for that list. The Gender list uses the rsGender recordset. The Age list uses the rsAge recordset etc....
