CodingForums.com - PHP/form insert statement to mysql

I'm trying to insert this form data into mysql database but I keep getting a server error what am I doing wrong?

Code:

<html> 

<head> 

  <title>Incidence Reporting</title> 

</head> 

<body> 

  <h2>Incidence Reporting</h2> 

<?php 

  

$db_s = "localhost";

$db_u = "bs_72";

$db_p = "tmmd2f";

$db_n = "bs_72";

$co = mysqli_connect($db_s,$db_u,$db_p)

or die('Error connecting to MySQL server.');



mysqli_select_db($co, $db_n);



  

  $first_name = $_POST['firstname'];

  $last_name = $_POST['lastname'];

  $e_mail = $_POST['email'];

  $when_it_happened = $_POST['whenithappened']; 

  $phone_number = $_POST['phonenumber']; 

  $i_description = $_POST['idescription']; 



  

  

  $query = “INSERT INTO las_cruces (first_name, last_name, e_mail, when_it_happened, “ .

  “phone_number, i_description) “ .

  “VALUES (‘$first_name’, ‘$last_name’,‘$e_mail’, ‘$when_it_happened’ , ‘$phone_number’, “ .

  “’$i_description’)”;

  



  

 $result = mysqli_query($co, $query);

  or die('Error querying database.');

   mysqli_close($co);

  

  

  echo 'Hello, ' . $first_name . ' ' . $last_name . '<br />';

  echo 'Thanks for submitting the form.<br />'; 

  echo 'Your email is ' . $e_mail . '<br />'; 

  echo 'Your phone number? ' . $phone_number . '<br />';

  echo 'The date of the incidence was ' . $when_it_happened . '<br />'; 

  echo 'What Happened: ' . $i_description . '<br />';
