I have tried altering the curly brackets but it still provides the same error

<?php

$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

$sql = "INSERT INTO posts (userid, artist, link) VALUES ('2', '".$_POST["artist"]."', '".$_POST["link"]."')";

if (mysqli_query($conn, $sql)); {
    echo "New record created successfully";


} else {
     echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}

mysqli_close($conn);
?>
