I am sorry to say this, even though I tried all lowercase uppercase conditions, I still get the same error. 


Notice: Undefined index: mySelect in C:\wamp64\www\example.php on line 36

Line 36:         echo "<tr><td>" . $row["mySelect"] . "</td></tr>";

You are missing an all-important line

$sql = "SELECT `$mySelect` as mySelect FROM employees";
$result = mysqli_query($link, $sql);                      //          add this line to query the database

 If still not working, post the code you now have.
