联系表单bootstrap php(Contact form bootstrap php)

 我会在这里挺身而出。 我真的不懂PHP，但我想用它为我正在构建的网站制作一个简单的电子邮件表单。 我把我认为可以工作的东西放在一起，但是当我点击提交时我仍然会收到错误。 
 
 任何人都可以告诉我，我做错了什么让它工作？ 
 
 这是代码（对不起，如果我发布了代码，我没有任何线索，问题是什么）： 
 
 Contact.html： 
 
  <h1 class="cover-heading">Contact Me</h1>
        <div class="form-area">
          <form role="form" method="post" action="Contact.php">
            <br style="clear:both">

            <div class="form-group">
              <input type="text" class="form-control" id="name" name="name" placeholder="Name"
                required>
            </div>
            <div class="form-group">
              <input type="text" class="form-control" id="email" name="email" placeholder="Email"
                required>
            </div>
            <div class="form-group">

              <span class="help-block"><p id="characterLeft" class="help-block ">You have reached the limit</p></span>

 这是错误：

"; echo "Please go back and fix these errors.

I'm going to be upfront here. I don't really know PHP, but I want to use it to make a simple email form for my website that I'm building. I have put together what I thought would work, but I still get errors when I click submit. 
 
Can anyone just tell me what I'm doing wrong to get it to work?
 
Here's the code (sorry if I over posted the code, I don't have the slightest clue where the problem is):
 
Contact.html:
 
  <h1 class="cover-heading">Contact Me</h1>
        <div class="form-area">
          <form role="form" method="post" action="Contact.php">
            <br style="clear:both">

            <div class="form-group">
              <input type="text" class="form-control" id="name" name="name" placeholder="Name"
                required>
            </div>
            <div class="form-group">
              <input type="text" class="form-control" id="email" name="email" placeholder="Email"
                required>
            </div>
            <div class="form-group">
              <input type="text" class="form-control" id="mobile" name="mobile" placeholder="Mobile Number"
                required>
            </div>
            <div class="form-group">
              <input type="text" class="form-control" id="subject" name="subject" placeholder="Subject"
                required>
