The username is set, so the first conditional evaluates to true.

Help me out here....What is happening to the variable that it's no longer containing the value "Treehouse" ?:) Thanks!

Nothing happens to the variable, it still contains "Treehouse".

As you state $username is set so the first if statement runs. The if statement that is nested inside checks if $username is not equal to "Treehouse", since it is actually equal to that the if statement does not run. The else statement in the code is attached to the first if statement, and since that did run the else statement does not run.

Meaning that ultimately nothing gets displayed after running the code.

Here is a version of the question code with some comments added:

<?php
$username = "Treehouse"; # Define $username and set it to "Treehouse"
if ($username) { # Check if $username is truthy (True)
    if ($username != "Treehouse") { # Check if $username is not "Treehouse" (False)
        echo "Hello $username"; # This does not run because the condition above is `False`.
    }
} else { # Run if connected `if` statement above did not run
    echo "You must be logged in"; # This does not run because the `if` statement above it ran.
}
