[RESOLVED] mysql_query dying with no error

[mrbaseball34]

In the code above, it is dying and not returning an error, all I'm getting is
"Error inserting debug info,"

Can't figure out why.

  function DebugLog($_mod, $_msg) {
    global $db_server;
    global $db_user;
    global $db_pwd;
    global $db;
    $_con2 = mysql_connect($db_server,$db_user,$db_pwd);
                mysql_select_db($db,$_con2);
    $sql = 'INSERT INTO `linv_debug_table` (line_id, proc_id, debug_msg, timestamp) VALUES (NULL, "'.$_mod.'", "'.$_msg.'", NULL)';
    $result = mysql_query($sql,$_con2);
    if(!$result) {
      die('Error inserting debug info,'.mysql_error($_con2));
    }
    mysql_close($_con2);    

  }

using this to call it:

  DebugLog("(".__LINE__.")", "Checking recaptcha answer");

Any ideas?
Yes, I can do an insert using the SQL produced with no problems.

Decided to go about it differently.
