Alt! ce l'ho fatta valutare la pagina 
L'errore che mi da ora è quersto:
codice:
Line 58, column 164: document type does not allow element "input" here; missing one of "p", "h1", "h2", "h3", "h4", "h5", "h6", "div", "pre", "address", "fieldset", "ins", "del" start-tag
...="0908c73a1a486ccf7c3fdb6195c825a4" />
The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.
One possible cause for this message is that you have attempted to put a block-level element (such as "
" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").
Giusto? Vuol dire che non hai racchiuso gli elementi hidden dentro un blocco, ovvero un paragrafo o un livello.
