Hi Kevin Parine! The problem actually lies in the declaration of the $fullName variable. To be honest, I'm not sure how it made it past the second step. When you first set up a variable, you assign it a value. This makes it no longer "undefined". Because you are using the .= as a concatenation operator instead of assigning the value $firstName $lastName to it, you are actually concatenting $firstName lastName onto something that is undefined.

The solution is to simply delete the .(period/full stop) from in front of the equals.

// You wrote
$fullName .= "$firstName $lastName";

// Should be

$fullName = "$firstName $lastName";

Hope this helps! :sparkles:

Thanks, your explanation was clear. I see why I was wrong to try and concatenate it.
