title: BootStrap Submit Button Not working
body: <p>I am trying to develop a simple front end for displaying images using BootStrap. However before using BootStrap the button to view images was working fine but after styling the page using bootstrap, It does nothing, Can anybody tell me what am I doing wrong?  When I tried seeing in Developer tools of Chrome , I get 2 exceptions:</p>
  
  <pre><code>Uncaught Error: You must include the utils.js file before tether.js
      at tether.js:4
  (anonymous) @ tether.js:4
  bootstrap.min.js:7 Uncaught ReferenceError: Tether is not defined
  </code></pre>
  
  <p>Code:</p>
  
  <pre><code>    &lt;html lang="en"&gt;
  
  
      &lt;head&gt;
          &lt;meta charset="UTF-8"&gt;
          &lt;meta http-equiv="X-UA-Compatible" content="IE=edge"&gt;
          &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt;
  
          &lt;title&gt;&lt;/title&gt;
          &lt;script src="script/tether.min.js"&gt;&lt;/script&gt;
          &lt;script src="script/tether.js"&gt;&lt;/script&gt;
          &lt;script src="script/jquery.min.js"&gt;&lt;/script&gt;
  
  
          &lt;link rel="stylesheet" href="css/bootstrap.min.css"&gt;&lt;/link&gt;
          &lt;link rel="stylesheet" href="css/styles.css"&gt;&lt;/link&gt;
  
          &lt;script src="script/bootstrap.min.js"&gt;&lt;/script&gt;
  
  
      &lt;/head&gt;
      &lt;body&gt;
          &lt;h1 class="mt-4" align='center'&gt; Demo Website &lt;/h1&gt;&lt;br&gt;
  
          &lt;div class="container" style="width:300px; background-color:ghostwhite;"&gt;
  
                  &lt;div class="form-group"&gt;
  
  
                  &lt;form  action='viewimages2.php' method="GET"&gt;
                      &lt;button class="btn-block btn btn-info" align='center' type="submit" name="Submit"&gt; View Images &lt;/button&gt;
                  &lt;/form&gt;
  
          &lt;/div&gt;
  
  
      &lt;/body&gt;
  &lt;/html&gt;

  <p>Working Code without Bootstrap:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
