                        <OPTION value=0
                          <? if($localid==0) {echo " selected ";}?>>select
                        <?

join the queries like:

$country2=mysql_query("select products.* from members,products where products.datanum='$localid' and members.id!=products.uid");

if not, explain your problem clearly.

your code not list any data in dropdown box.
three user add any list of member in my work office. For each user insert datanum to database example :
id | name | datanum |
1 | john | 2 |
2 | test | 1 |
3 | char | 3 |
4 | bovi | 1 |
5 | nume | 1 |

Now For each member add products Example : ( Uid = member id )

id | uid | productname | datanum |
1 | 2 | php12345678 | 2 |
2 | 5 | java1234678 | 1 |
3 | 4 | webdesign | 1 |
4 | 3 | logodesign | 3 |
5 | 1 | .net | 3 |
6 | 2 | testtes | 3 |

my url for each user is : mydomain.com/index.php?id=1/2/3 etc..
Now i want to list member in combobox( dropdown box ) when :

id = datanum ($localid=$_GET["id"];)
and uid != products . (filter member was in products)
