html - PHP Contact form not sending email. Not sure if syntax or Server -

hey guys have html document contact form created , not working. have php in seperate php file so:

html:

<form class="form-horizontal" action="form_process.php" method="post" name="contact_form">     <div class="form-group">         <label class="col-sm-2 control-label white-color">email</label>         <div class="col-sm-10">             <input type="email" class="form-control" name="email" placeholder="email" required>         </div>     </div>     <div class="form-group">         <label class="col-sm-2 control-label white-color">name</label>         <div class="col-sm-10">             <input type="text" class="form-control" name="name" placeholder="first name" required>         </div>     </div>     <div class="form-group">         <label class="col-sm-2 control-label white-color">message</label>         <div class="col-sm-10">             <textarea class="form-control" rows="5" placeholder="type message here!" name="message" required></textarea>             <button type="submit" class="btn btn-default btn-lg text-center" id="send-btn" name="submit">send</button>         </div>     </div> </form> 

and here php:

<?php  if (isset($post['name']) && isset($_post['email'])) {      $email = $_post['email'];     $name = $_post['name'];     $message = $_post['message'];      $to = 'j_goris@live.com';     $subject = 'jorgegoris.com form submission';     $text = "name: ".$name."\n"."email: ".$email."\n". "wrote following: "."\n\n".$message;      if(mail($to, $subject, $text, "from: ".$name)){         echo '<h1>thanks! shortly.</h1>';     }     else {         echo 'sorry there error! please try again.';     } }?> 

this first time tackling php contact forms. uploaded files server , still no dice. can guys see whats wrong?

replace:

$post['name'] 

to:

$_post['name'] 

replace:

if(mail($to, $subject, $text, "from: ".$name)){ 

to:

if(mail($to, $subject, $text, "from: ".$email)){ 

full code:

<?php  if (isset($_post['name']) && isset($_post['email'])) {      $email = $_post['email'];     $name = $_post['name'];     $message = $_post['message'];      $to = 'j_goris@live.com';     $subject = 'jorgegoris.com form submission';     $text = "name: ".$name."\n"."email: ".$email."\n". "wrote following: "."\n\n".$message;      if(mail($to, $subject, $text, "from: ".$email)){         echo '<h1>thanks! shortly.</h1>';     }     else {         echo 'sorry there error! please try again.';     } } ?>
