What type of variable is $my_values? It seems to be an array.

PHP Code:

    while ($my_value=$db->fetch_array($my_values)  //this while loop goes through the array entry by entry.  If there were 10 instances of field5 = $some_var from earlier, this code would be executed 10 times - once for each entry 


$db->fetch_array() needs a MySQL resource as parameter, not a simple array.
