Full Stack JavaScript Techdegree Graduate 16,462 PointsThank you David for a quick reply! Unfortunately still a challenge!
<?php
$title = "Dr."; $firstName = "David"; $lastName = "Bowman";
$fullName = "$title " . "$firstName " . "$lastName "; echo $fullName;
echo "The lead character from 2001: A Space Odyssey is named ____";
?>
The preview shows correct but I get the message:
Bummer! Make sure $fullName is set to the concatenation of $title, $firstName, and $lastName, with spaces in between.

<?php
$title = "Dr.";
$firstName = "David";
$lastName = "Bowman";
$fullName = $title . " " . $firstName . " " . $lastName;
echo "The lead character from 2001: A Space Odyssey is named ____";
?>
We are assigning the variable $title a white space (" "), the variable $firstName another white space (" ") and finally the variable $lastName. All that using . (dots) to concatenate. I hope that helps a little bit.

For the one who has the same challenge remember not to add a space after $lastName - even though it looks weird and is connected to the echo without a space: "Dr. David BowmanThe lead character from 2001: A space Odyssey is Named ___";

25,940 PointsI think if you echo out $fullName you will see what you are doing wrong. You are actually concatenating each variable to its text equivalent, so "Dr. Dr." etc. You just need to concatenate the variables (with added spaces).
