The attribute value "blur()" for the "onfocus" attribute was not enclosed in single or double quotation marks when it must be. In HTML 4.01, attribute values containing characters other than A-Z, a-z, 0-9, hyphens, periods, underscores, and colons must be quoted. In XHTML/XML, all attribute values must be quoted. Quotes are recommended even if they are not required.
Also at line 41 the end tag for "SCRIPT" was found, but "SCRIPT" was never opened, has been ended too many times, or cannot have an end tag.
