MailerPHP

Hi, I got a small problem where if I run the run.php which I created in the composer MailerPHP folder with the simple code to send an email, which works find, but the problem comes when it I am trying to run the code from a form.

Here is the form code, the html is in the root directory of the folder. The run is in the mailer/run.php. 

         <form name="sentMessage" id="contactForm" action="mailer/run.php">
           <div class="control-group">
             <div class="form-group floating-label-form-group controls">
               <label>Name</label>
               <input value="Josh" type="text" class="form-control" placeholder="Name" id="name" required data-validation-required-message="Please enter your name.">
               <p class="help-block text-danger"></p>
             </div>
           </div>
           <div class="control-group">
             <div class="form-group floating-label-form-group controls">
               <label>Email Address</label>
               <input value="[email protected]" type="email" class="form-control" placeholder="Email Address" id="email" required data-validation-required-message="Please enter your email address.">
               <p class="help-block text-danger"></p>
             </div>
           </div>
           <div class="control-group">
             <div class="form-group col-xs-12 floating-label-form-group controls">
               <label>Phone Number</label>
               <input type="tel" class="form-control" placeholder="Phone Number" id="phone" required data-validation-required-message="Please enter your phone number.">
               <p class="help-block text-danger"></p>
             </div>
           </div>
           <div class="control-group">
             <div class="form-group floating-label-form-group controls">

               <p class="help-block text-danger"></p>
