A document must not include both a “meta” element with an “http-equiv” attribute whose value is “content-type”, and a “meta” element with a “charset” attribute.
Bad start tag in “div” in “head”.
Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Attribute “onchahge” not allowed on element “input” at this point.
The element “h4” must not appear as a descendant of the “th” element.
