Help for a new guy

Hi William, thanks for the text version of the uploads, easier to help you make the changes. Should be easy for you to do.

Detailed instructions on theming

Archive File
Create a copy of archive.php and call it archive-listing.php and place in theme folder.

In that file is a line

get_template_part( 'content', get_post_format() );

Replace it with

if ( function_exists('epl_property_blog') ) {
    echo epl_property_blog();
}

Single File
Create a copy of single.php and call it single-listing.php and place in theme folder.

In that file is a line

<?php get_template_part( 'content', 'single' ); ?>

replace with

<?php if ( function_exists('epl_property_single') ) {
    echo epl_property_single();
} ?>

Let me know how you go
