PHP If/Else Statement

[idesign123]

This is probably REALLY easy for most of you, but I'm a newbie.

I have a piece of PHP code that works fine...

<?php if((get_post_meta($post->ID, "intro-text", true))) { ?>
<?php the_field('intro-text'); ?>
<?php } ?>

What I want to do is change it to an "if/else" statement (something simple like "else echo 'sorry no intro text'").

I tried modifying the if/else statements on other websites, but it's generating errors. Can someone please tell me the correct format?

Thank you in advance.

<?php

    the_field('intro-text');
} else {
    echo "sorry no intro text";
}
