Can you post the code you're entering?

Hi, Andrew. The code is:

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

$number=$checker->number=16661;

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

?>

The correct answer would be the following:

<?php

include('class.palprimechecker.php');
$checker=new PalprimeChecker;
$number=$checker->number=16661;



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

?>

Do you see where you went wrong in the if statement?

Vaidas,

It looks like you chained methods together improperly. The code above from the mod shows it correctly where you chained a method but the last method ->$number should have been an argument to isPalprime()
