Below are the results of checking this document for XML well-formedness and validity.

   1. Error Line 72 column 144: 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.

      ...="de36ba162658efa6816e772e53f3a800" />

      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 "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").

      ✉
   2. Error Line 73 column 56: 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.

              <input name="id_sondy" type="hidden" value="1" />

      ✉
   3. Error Line 74 column 10: character data is not allowed here.

                sonda o ...

      You have used character data somewhere it is not permitted to appear. Mistakes that can cause this error include putting text directly in the body of the document without wrapping it in a container element (such as a <p>aragraph</p>) or forgetting to quote an attribute value (where characters such as "%" and "/" are common, but cannot appear without surrounding quotes).

      ✉
   4. Error Line 75 column 12: end tag for "form" omitted, but OMITTAG NO was specified.

             </div>

      You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".

      ✉
   5. Info Line 72 column 8: start tag was here.

              <form action="././sonda/kernel/zapis.php" method="post"><input type="hid

   6. Error Line 104 column 57: end tag for element "form" which is not open.

            <ins><input type="submit" value="Zagłosuj" /></form></ins>

      The Validator found an end tag for the above element, but that element is not currently open. This is often caused by a leftover end tag from an element that was removed during editing, or by an implicitly closed element (if you have an error related to an element being used where it is not allowed, this is almost certainly the case). In the latter case this error will disappear as soon as you fix the original problem.

      If this error occured in a script section of your document, you should probably read this FAQ entry.
