Assistance with elseif [closed]

Okay. I figured out how to do this. I assigned a variable to use the value of the custom meta field, which just made things a little easier to visualise (for me):

<?php 
    $intro_para_value = get_post_meta(get_the_ID(), 'intro-para', true );
    if ( has_post_thumbnail() ) { print get_the_post_thumbnail(get_the_ID(), 'homefeature_thumb'); }
    elseif ( !empty ($intro_para_value)) { echo $intro_para_value; }
    else { echo get_limited_excerpt('', '', 230); }
?>

Hope this helps others who might be stuck.
