I see on many reply in other post to change "register_globals" to On, but many says that it's already done and it doesn't work. So i'll say that a very small and hidden error in script can be the cause. Just look at that code and try to find the error (small and hidden error)

$DS = mysql_query("SELECT * FROM master WHERE Edition="DS");

echo "<table border='1'>\n";
echo "<caption>8ieme Édition</caption>\n";
echo "<TR>\n<TD>Nom</TD>\n<TD>Coût</TD>\n<TD>Type</TD>\n<TD>Rareté</TD>\n<TD>Couleur</TD>\n<TD>Texte</TD>\n<TD>P/T</TD>\n<TD>Artiste</TD>\n<TD>Nombre</TD>\n</TR>\n";

while ($ligne = mysql_fetch_object($DS))
{
 echo "<TR>\n<TD>$ligne->Name</TD>\n<TD>$ligne->Cost</TD>\n<TD>$ligne->Type</TD>\n<TD>$ligne->Rarity</TD>\n<TD>$ligne->Color</TD>\n<TD>$ligne->Text</TD>\n<TD>$ligne->P/T</TD>\n<TD>$ligne->Artist</TD>\n<TD>$ligne->Number</TD>\n</TR>\n";
}
echo "</table>\n";

Do you see the error?? Hum, not so easy to see. It's on the first line. At the end. Yes. $DS = mysql_query("SELECT * FROM master WHERE Edition="DS"); The error is Edition="DS" should be Edition='DS'". That small programing error = Error 200. So the only thing i would say is BE CAREFUL WITH SMALL AND HIDDEN PROGRAMING ERROR
