Hi all Probably simple, but my brain is near mush. I need my page to validate to XHTML1.0 but have this link: http://www.nationaltrust.org.uk/scripts/nthandbook.dll?ACTION=PROPERTY&PROPERTYID=5 That, because it contains reserved characters, is causing my page not to validate. I've tried encoding the ? with %3f and the = with %3d etc, but the URL then won't play with the national trust's server. Is there a way out of this? Regards Francis
