Display related table fields for each listing on a LIST page

Hello, All.

I'm attempting to display data on a LIST page from a related table using a "List Options from Database" radio field.

No errors appear, but neither does the related 'website_url' field or other related fields.

Setup for the "gallery_showing" radio field in the 'paintings' table:
 Get Options from database (advanced)
 Section Tablename = galleries
 Option values = num
 Option labels = gallery_name

// Get list of paintings
  list($paintingsRecords, $paintingsMetaData) = getRecords(array(
    'tableName'   => 'paintings',
    'where' => ' category LIKE "%available%" ', 
    'loadUploads' => true,
    'allowSearch' => false,
    'loadCreatedBy' => false,
  ));
  
  // load records from 'galleries'
  list($galleriesRecords, $galleriesMetaData) = getRecords(array(
    'tableName'   => 'galleries',
    'loadUploads' => true,
    'allowSearch' => false,
    'loadCreatedBy' => false,
  ));

-------------

<?php foreach ($paintingsRecords as $record): ?>

 
 <?php // load info from 'paintings' table
       foreach ($record['painting'] as $index => $upload): ?>
         <img src="<?php echo htmlencode($upload['thumbUrlPath2']) ?>">
      <?php endforeach ?> 
     
     
  <?php // load record from 'galleries' table
      // that matches this painting's selection for "gallery_name"   
           list($galleriesRecords, $galleriesMetaData) = getRecords(array(
          'tableName'   => 'galleries',
          'where'       => "`num` = ".$record['num'],
          'allowSearch' => false,
          'limit'       => '1',
     ));
    ?> 
    
  <?php // display all 'galleries' table related fields
           if (!empty($galleriesRecord['website_url'])): ?>
           Website: <?php echo htmlencode($galleriesRecord['website_url']) ?>
           <?php else: ?>
           (No website)
           <?php endif ?>
    
    [... do same for other related fields ...]
    

<?php endforeach ?>

The code below is mostly based on code from another project, but I can't determine the differences. Hope I'm at least headed in the right direction?

Thanks in advance for any insights!
