PHP sendmail doesn't return data from select form

[numerouno]

My new HTML form contains a number of drop down select boxes. However when the form is submitted this data does not get emailed, it just comes back blank. I am using the $_POST command to return data.
Can anyone explain why this may be happening?

It's hard to say anything without the source code. Did you set the value attributes on the option tags properly?

The HTML code for drop down selection box is:

<label for="title"><span>Title</span>
<select name="title">
<option value=>Mr</option>
<option value=>Mrs</option>
<option value=>Miss</option>
<option value=>Ms</option>
<option value=>Dr</option>
</select>
</label>

and PHP Sendmail code for selection box is: $_POST['title']

They don't have values:
<label for="title"><span>Title</span>
<select name="title">
<option value=>Mr</option>
<option value=>Mrs</option>
<option value=>Miss</option>
<option value=>Ms</option>
<option value=>Dr</option>
</select>
</label>

Should be something like
<label for="title"><span>Title</span>
<select name="title">
<option value="Mr">Mr</option>
<option value="Mrs">Mrs</option>
<option value="Miss">Miss</option>
<option value="Ms">Ms</option>
<option value="Dr">Dr</option>
</select>
</label>
