Undefined variable?

[lurtnowski]

I’m getting
Notice : Undefined variable: conn in C:\Users\lurtnowski\webserver\htdocs\DCT\2\reports\added_deviices.php on line 17
on

$result = mysqli_query($conn, $query);

But when I

echo '<pre>';
print_r(get_defined_vars());
echo '</pre>';

Its there.

Why is it undefined?
