Allora, inanzitutto grazie, poi la convalidazione ora trova la definizione che pero' non e' valida per html 4.01 transitional e i 24 errori portano quasi tutti lo stesso errore
You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).

Oppure The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).

Continuo a non avere idea di quello che faccio VVoVe:
Ciao
