I'm having a bit of trouble getting a contact form to function correctly. The template did not come with any contact related php of js. I have managed to get it to send the email fine. But the content of the email is not being sent. If possible, I would like some help with my contact.php. Below is my code:

HTML
Code:
<form action="contact.php" method="post">
					    	<div>
					    		<input type="text" class="textbox" value="Name (Required)" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Name';}">
						    	
						    </div>
						    <div>
						    	<input type="text" class="textbox" value="Email (Required)" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Email';}">
						    </div>
						    <div>
						     	<input type="text" class="textbox" value="Subject" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Subject';}">
						    </div>
						    <div>
						    	<textarea value="Message:" onfocus="this.value = '';" onblur="if (this.value == '') {this.value = 'Message';}">Describe Your project in detail...</textarea>
						    </div>
							<label>*What is 2+2? (Anti-spam)</label>
<input name="human" placeholder="Type Here">
<input type="hidden" name="send" >
						    <button class="btn btn-8 btn-8c">Submit</button>
					    </form>
