nessuno sa proprio aiutarmi?

ecco il mio form:

<form method="POST" action="<%=MM_editAction%>" name="form1">
<table width="200" align="center">
<tr valign="baseline">
<td width="192"> <div align="center">
<input name="numero" type="text" value="<% Response.Write Request.QueryString("numero") %>" size="13" maxlength="13">
</div></td>
</tr>
<tr valign="baseline">
<td height="35"> <div align="center">
<input type="submit" value="Inserisci">
</div></td>
</tr>
</table>
<input type="hidden" name="MM_insert" value="form1">
</form>
