How to get the list of answers from a single author?

I’m trying to display the list of answers using the following query

<? php
$answers = new WP_Query( ‘post_per_page=20&orderby=post_date&post_type=dwqa-answer&author=’.get_query_var(‘author’) );
if ( $answers->have_posts() ) {
echo ‘<div class=”widget dwqa-widget dwqa-latest-questions”>’;
echo ‘<ul>’;
while ( $answers->have_posts() ) { $answers->the_post( );
echo ‘
<li><a href=”‘.get_permalink().'” class=”question-title”>’.get_the_title( ).'</a>’ . human_time_diff( get_the_time( ‘U’ ), current_time( ‘timestamp’ ) ) . ‘ ago’;
‘</li>’;
}
echo ‘</ul>’;
echo ‘</div>’;
}
wp_reset_query( );
? >

However this will only return the questions where the answer is. It doesn’t return the actual answer from the author. I’m a PHP noob so could anyone guide me on how I could return a list of answers and NOT the questions where the answer is?

Thanks!
