I'm almost there. What am I missing?

I have no idea what I am missing and I can't seem to find other answers online. I've done everything except the concatenation doesn't seem to be working. What's up?

palprimes.php 
<?php
include("class.palprimechecker.php");
$checker = new PalprimeChecker();
$checker->number = 17;




echo "The number " . $number . " ";
echo "(is|is not)";
echo " a palprime.";


?>

Your problem is in the first echo change the $number with $checker->number

<?php

include("class.palprimechecker.php");
$checker = new PalprimeChecker();
$checker->number = 17;


echo "The number " . $checker->number . " ";
echo "(is|is not)";
echo " a palprime.";

?>

Also PalprimeChecker is an Object not a Method, so you shouldn't be using the parenthesise at the end.

$checker = new PalprimeChecker(); // not this way!

$checker = new PalprimeChecker; // THIS WAY!!

Thank you for that input. I was wondering about that.
