Stray end tag “noscript”.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.

The first child “option” element of a “select” element with a “required” attribute, and without a “multiple” attribute, and without a “size” attribute whose value is greater than “1”, must have either an empty “value” attribute, or must have no text content. Consider either adding a placeholder option label, or adding a “size” attribute with a value equal to the number of “option” elements.
A document must not include more than one “autofocus” attribute.
Duplicate ID “submit-parent-contact-form”.
Element “style” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
