Can't submit data in textarea - php

Question

This is my code, I'm trying to get data inside #download div and submit it to other file test2.php
Don't worry it is just table inside #download
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<form action="test2.php" method="post">
<textarea style="" id="file" name="file"></textarea>
<input type="submit">
</form>
<script>
$(document).ready(function(e) {
var html=$('#download').html();
$('#file').val(html);
});
</script>
<div id="download">
<div id="content">
<table border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
<td colspan="7" id="info"></td>
</tr>
<tr>
<td colspan="7" id="info_space"></td>
</tr>
<tr>
<td valign="top" class="sirinaStupca"><!-- 1. STUPAC -->
</tr>
</table>
</div>
</div>
Other file just needs to echo it, for testing purpose, but it throws me an error: Error 404
Unable to resolve the request "test2.php". When I put normal text or css() instead of table it is working. I can't figure it out why.
if(isset($_POST["file"]))
{
echo $_POST["file"];
}
