Hi, i need put data from variables into MYSQLI statement but something gone wrong and I keep getting this message:

Parse error: syntax error, unexpected '$nr' (T_VARIABLE) in E:\xampp\htdocs\test3\zgloszenie.php on line 13

My PHP code:

<?php
$host='localhost';
$user='root';
$pass='';
$db='ratownictwo';
$nr = $_POST['nzr'];
$ndz = $_POST['nd'];
$adde = $_POST['add'];
echo $nr;


$conn=mysqli_connect($host,$user,$pass,$db);
$q = 'INSERT INTO `zgloszenia` (ratownicy_id, dyspozytorzy_id, adres, pilne, czas_zgloszenia) VALUES ('$nr','$ndz','$adde', 0, CURRENT_TIME)';
$ress= mysqli_query($conn, $q) or die ('Coś poszło nie tak');
mysqli_close($conn);
?>

AND piece of HTML code:

<div class="glowny">
            <h2>Dodaj nowe zgłoszenie</h2>
            <form action="zgloszenie.php" method="POST">
                <label for="nzr">Numer zespołu ratowniczego</label><br/>
                <input type="number" name='nzr'><br/>
                <label for="nd">Numer dyspozytora</label><br/>
                <input type="number" name='nd'><br/>
                <label for="add">Adres</label><br/>
                <input type="text" name='add' size="100"><br/>

                <input type="reset" value='WYCZYŚĆ'>
                <input type="submit" value='ZGŁOŚ'>
            </form>

        </div>

Data from form section are normally passed into PHP code but my SQLi syntax cant read this things and put into them.
