<fieldset>
<label class="name">
<input type="text" value="Your Name" onFocus="if(this.value=='Your Name'){this.value=''}" onBlur="if(this.value==''){this.value='Your Name'}">
</label>
<label class="phone">
<input type="text" value="Telephone" onFocus="if(this.value=='Telephone'){this.value=''}" onBlur="if(this.value==''){this.value='Telephone'}">
</label>
<label class="email">
<input type="email" value="Email" onFocus="if(this.value=='Email'){this.value=''}" onBlur="if(this.value==''){this.value='Email'}">
</label>
<label class="message">
<textarea onFocus="if(this.value=='Message'){this.value=''}" onBlur="if(this.value==''){this.value='Message'}">Message</textarea>
</label>
<div class="btns"> <a class="button" onclick="clearFunction()" >Clear</a> <a class="button" type="submit" name="submit" value="Send Form" >Send</a> </div>
</fieldset>
</form>

Answer 1

you are use <a> tag to submit the form
replace <a class="button" type="submit" name="submit" value="Send Form" >Send</a> with <input class="button" type="submit" name="submit" value="Send Form" >

Answer 2

You are not naming any inputs in your form..
<input **name='name'** value='Your name'>
<input **name='phone'** value='Phone'>
and so on..
for proccessing:
if(isset($_POST['submit'])){
$name=$_POST['name'];
$phone=$_POST['phone'];
$xxx=$_POST['xxx'];
echo $name, $phone; //echoing data.
}
and so on.
Don't forget to sanitize your data before submitting..(ANTI-SQL INJECTION)
and instead of your OnBlur and OnFocus solution: placeholder='Your name'
