Need help with objects quiz in php

Here's the link (5/7):

http://teamtreehouse.com/library/programming/build-a-simple-php-application/wrapping-up-the-project/objects

<?php

    include("class.palprimechecker.php");

    $checker = new PalPrimeChecker();

    $checker->number = 17;

    echo "The number 17 ";
    if ( $checker.isPalprime() ) {
        echo "is"
    } else {
        echo "is not"
    }
    echo " a palprime.";

?>

May I ask what I'm doing wrong?

Very close. It looks you like you are using syntax from another programming language. :~) In many programming languages, a dot (.) is used after an object name to identify a method or a property inside that object. PHP uses the two characters that together look like a single arrow (->) instead.

Where you have this --

$checker.isPalprime()

-- you should have this --

$checker->isPalprime()

Does that help?
