so im working on an php script that will do a couple of things. First it will take ip,email, and two dates from a user in a form. It will insert these into a table and then using the IP as the key, it will remove the row from table 1(the original table) into table 2(identical to table 1 except with addition of IP,email and two dates. I keep getting undefined comment error, not sure why and also, no SQL action is performed. Any help or guidance will be appreciated!
   <?php
   $connect = mysqli_connect("reserve1", 
   "root", "","server_31");
   $status = "";
   if(isset($_POST['new']) && 
   $_POST['new']==1){
   $IPAddress = $_REQUEST['IPAddress'];
   $email = $_REQUEST['email'];
   $Date_reserved = 
   $_REQUEST['date_reserved'];
   $Date_returned = 
   $_REQUEST['date_returned'];
   $sql="INSERT INTO 'servers_in_use'
   (`IPAddress`,'Email'`Date_Reserved`, 
    `Date_Returned`,) VALUES
   ('$IPAddress','$email','$Date_reserved',  
    '$Date_returned',)";
  $sql="INSERT INTO 'servers_in_use'    
   SELECT * FROM 'servers' WHERE IPAddress= 
  $IPAddress";
  $sql="DELETE FROM servers   WHERE 
  IPAddress =$IPAddress";
   mysqli_query($connect, $sql);
 }
 ?>
