Hi there, I have a file field called fees_file_upload. I'm trying to provide the file as a download in my page (using Oxygen) but the codse samples given just give me an error. I'm trying to use this snippet:
```
<?php $files = rwmb_meta( 'fees_file_upload' ); ?>
<h3>Uploaded files</h3>
<ul>
    <?php foreach ( $files as $file ) : ?>
        <li><a>"><?= $file['name']; ?></a></li>
    <?php endforeach ?>
</ul>
```
But I get the following error:
Warning: foreach() argument must be of type array|object, string given in /home/customer/www/duod37.sg-host.com/public_html/wp-content/plugins/oxygen/component-framework/components/classes/code-block.class.php(133) : eval()'d code on line 4

How can I get the URL of the file to use in my page?

Sorry this is the code snippet:
```
<?php $files = rwmb_meta( 'fees_file_upload' ); ?>
<h3>Uploaded files</h3>
<ul>
    <?php foreach ( $files as $file ) : ?>
        <li><a href="<?= $file['url']; ?>"><?= $file['name']; ?></a></li>
    <?php endforeach ?>
</ul>
```

Hello Andrew,

Please try to add the specific post ID to the helper function rwmb_meta() and check if it works:

<?php $files = rwmb_meta( 'fees_file_upload', '', 123 ); ?>

where 123 is the post ID. Following the documentation https://docs.metabox.io/functions/rwmb-meta/
