我的PHP _POST有什么问题，它从表单中接收除了一个以外的所有值？

Question

I am making an online order form for the company at which I am an intern, and the form has 23 fields of misc. types. When the end user hits submit, the form.html posts data to process.php. The issue I am having is that the data from all of my fields gets posted, except for the data from one field. I have checked my spelling and stuff, and the php code looks valid. Below is the relevant code from both files, and thank you in advance for your help.

form.html full file here http://pastebin.com/MRwE8jE3

<li id="li_8" >
    <label class="description" for="prefangle">Preferred Angles </label>
    <div>
        <textarea id="prefangle" name="prefangle" class="element textarea medium"></textarea>
    </div>
</li>

process.php full file here http://pastebin.com/bSfHbt16

<tr><td>Preferred Angles: </td><td>".$_POST['prefangle']."</td></tr>

Any and all help is appreciated.

Answer 1

For unknown reason, I couldn't add a comment to your question (O.O) so I'm posting it as answer (tho I do not consider it as answer, just a tip)

However, on the top of process.php, add

print_r($_POST);

And you'll see all the data passedby POST request :)
