opencart产品URL属性是可点击的

I am using Opencart v2.2.0 and I am trying to make the URL attribute of each product clickable. Right now I see the link, but it isn't clickable. I found out the attribute ID of URL attribute and I have the following code:

  <?php foreach ($attribute_group['attribute'] as $attribute) { ?>
<?php if ($attribute['attribute_id'] == 102) { ?>
            <tr>
               <td><?php echo $attribute['name']; ?></td>
              <td><a href="<?php echo $attribute['text']; ?>"><?php echo $attribute['text']; ?></a></td>
            </tr>
<?php } else { ?>
        <tr>
          <td><?php echo $attribute['name']; ?></td>
          <td><?php echo $attribute['text']; ?></td>
        </tr>
        <?php } ?>
      <?php } ?>

But it still isn't clickable. Does anyone have a suggestion, please? I do not know what else to do and what am I doing wrong.
