how can i put an HREF inside an IF ELSE ?

im using justin tadlocks sliding plugin which gives the original call like so

<a class="open" title="
<?php _e('Open panel', 'sliding-panel'); ?>">
<?php _e('Open <span class="arrow">↓</span>', 'sliding-panel'); ?>
</a>

and i want make something like this –

<?php
if ( is_user_logged_in() ) {
    echo '<a href="<?php echo wp_logout_url( get_permalink() ); ?>"
title="Logout">Logout</a>';
} else {
    echo '
<a class="open" title="
<?php _e('Open panel', 'sliding-panel'); ?>">
<?php _e('Open <span class="arrow">↓</span>', 'sliding-panel'); ?>
</a>';
}
?>

however its getting an href inside a if else statement, its just not doing it!!

any ideas here, i thought probably i can build a custom function with the URL and put that in, but ive no idea how to go about that.

thanks for any tips!!
