Hi guys, please have a look at index.php3 and tell me why we are using a syntax like this: . '&hash=' . This gives something like this in the HTML source: <frame src="left.php3?lang=en-iso-8859-1&server=1&hash=e08aa7a1fba5bb03ef59b3c68b655fda" name="nav" frameborder="0" /> Wouldn't be better to generate this: <frame src="left.php3?lang=en-iso-8859-1&server=1&hash=e08aa7a1fba5bb03ef59b3c68b655fda" name="nav" frameborder="0" /> ? I am looking for a bug where left.php3 complains about not receiving hash (I cannot reproduce it here). Thanks. Marc
