ho inserito questo form

<form name="ricerca" action="ricerca.asp" method="post" style="margin:0;">
<label for="ric">ricerca nel sito </label>
<input type="text" size="10" id="ric" name="ric" />
<input name="invia" type="submit" class="pulsante" id="invia" accesskey="r" tabindex="2" title="invia" value="Ricerca">
</form>
facendo il controllo del codice HTML ho questi errori:

Error Line 42 column 26: document type does not allow element "LABEL" here; missing one of "P", "H1", "H2", "H3", "H4", "H5", "H6", "PRE", "DIV", "ADDRESS" start-tag.

...dex="2" title="invia" value="Ricerca">
Error Line 45 column 14: end tag for "FORM" which is not finished.

</form>
come posso correggere questi errori?
