I'm unsure why i'm being told in the quiz that $fullName is not properly concatenated. Can someone advise?
<?php
$title = "Dr.";
$firstName = "David";
$lastName = "Bowman";
$fullName .= $title . $firstName . $lastName;
echo "The lead character from 2001: A Space Odyssey is named ____";
?>

You're joining all the words, but you still need a couple of spaces to keep them all from running together. Also the assignment should be just a plain "=" (not ".=").

231,198 PointsThose don't get added into the string. To get spaces into the string, they need to be literal strings (made by surrounding each space in quotes). Those can then be concatenated with extra periods. Example:
<?php
$bothWords = $firstWord . " " . $nextWord;
