Nu-mi apare nimic, dar de cec?

...?!

Acum am inteles ce mi-ai aratat, un cod face cat o mie de vorbe. Merci mult. Sa vad cum fac cu afisarea asta...

--- Later Edit --- (ca mi-a fost lene sa apas "Edit")

Desi am pus codul cum trebuie, nu inteleg.. nu-mi afiseaza nimic.. Cred ca gresesc un caracter ceva, dar nu-mi dau seama unde..
Cod PHP:
<?php
    $host="localhost";
    $username="";
    $password="";
    $db_name="";
    mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
    mysql_select_db("$db_name")or die("cannot select DB");
    $sql="SELECT * FROM angajati,adev_gen where angajati.id_angajat=adev_gen.angajat_id"; 
    $result=mysql_query($sql);
    while($rows=mysql_fetch_array($result)){
?>
<tr> 
    <td><input type="checkbox"></td> 
    <td><?php echo $rows['ang_nume']; ?></td> 
    <td><?php echo $rows['adev_gen_nr']; ?></td> 
    <td><?php echo $rows['adev_gen_data']; ?></td> 
    <td><?php echo $rows['adev_gen_serveste']; ?></td>
</tr> 
<?php
    // close while loop 
    }
    // close connection 
    mysql_close();
?>
