No return from code

Don't know why i'm getting errors with this code. 

 <?php
        //this is the description of each area containing PDFs
        $living = get_field( "living_desc" );

        //this checks is the row has data
        if( have_rows('living_skill') ):

            //this is a repeater in a while loop
            while ( have_rows('living_skill') ) : the_row();

                //these are sub fields
                $title   = get_sub_field('title');
                $file    = get_sub_field('file');

            ?>
                <p><?php echo $title ?></p>
                <p><?php echo $file ?></p>

This doesn't seem related to any given challenge, so we might need more information to do any kind of debugging (what is the error exactly?). At a quick glance, i can't see anything too wrong with it, apart from being a fragment (hence not using $living, featuring endif, endwhile). I assume this is wordpress (a theme?). At risk of stating the obvious can you not echo and var_dump to trace the flow and variable values, and narrow down the bug to a specific point. so test the value of living, test that your getting in the if, then put an output in the while to confirm getting in there, and confirm the row is what you think it is. Systematically check your assumptions. If your code is solid, then maybe you don't have access to something you thought you did.

If the code is getting inside the if condition and the while loop, then use var_dump to take a look at the row. something like $row = get_row(); should get the row (try to confirm data structure is consistent with the sub field names you're using). If you're not getting inside if, or while at all, then your problem is earlier.
