You have two post buttons in the markup.
<tr> <button id="post" class="post">post</button></tr>
</table>
<div><label>Description</label></div>
<div><textarea rows="3" cols="40"> </textarea></div>
</form>
<button id="post" class="post">post</button>
Your button:
<button id="post" class="post">post</button>
is repeated twice in the markup posted.
