Hello, the error is that the variable you are echoing is using a hyphen $num-one while the one that you set uses an underscore $num_one. Ensure they are the same and give it another try : )

In fact, hyphens are not allowed in variable names at all. So you should change $num-three to $num_three. Also it appears you added a space between <? and php, there can be no space, it has to be <?php.

Please paste your code here so we could take a look. Keep in mind that in the console since you did not specify a new line character, the variable shows up right BEFORE the "treehouse:~/workspace$" prompt.

<?php
$num_one = 1;
$num_two = 2;
$num-three = 3;

echo $num-one;
?>
