Mail Script Error

[ShadyCoco]

Hey, I've been working on a mail script and keep coming accross little errors.

I've fixed most of them but now I'm getting this one:

Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\wamp\www\***\mail.php on line 39

I don't understand because my mysql_fetch_array() is bringing resources :/

If anyone can point me the right way i'd be very happy :)

Heres the code:

$_MailRun = mysql_query("SELECT * from `mails` ORDER BY `time` DESC");

//this is line 39
while ($_Mails = mysql_fetch_array($_MailRun, MYSQL_ASSOC)) 
{

   if ($_Mails['to'] == $_USER['id']) 
{
    $_MailsFrom = $_USERMAILFROMcol['username'];
 $subject = ($_Mails['subj'] == "") ? "No Subject" : $_Mails['subj'];
 if ($_Mails['seen']=="1")
 {
	 $_MailSeen="No";
 }
 else
 {
	 $_MailSeen="Yes";
 }
   echo "

					<tr>

						<td colspan='25%'>".date(F." ".d.", ".Y." ".g.":".i.":".sa,$_Mails['time'])."</td>

						<td width='25%'><a href='mail.php?mail=read'>".$subject."</a></td>

						<td width='25%'>".$_MailsFrom['username']."</td>

						<td width='25%'>".$_MailSeen."</td>

						<td><a href='mails.php?mail=delete'>Delete</a></td>

					</tr>



";

}

}
?>
