Call upsell.phtml in custom phtml file

Question

I am working in the view.phtml file at the moment. In this file, I am using a custom .phtml file called product.info.phtml. I called it like this:

<?php echo $this->getChildHtml('product_additional_data') ?>

And in the local.xml I called the file like this:

<reference name="product.info.additional">
 <block type="core/template" template="custom/product.info.phtml" name="productInfoTabs" after="-"/>
</reference>

Which works just fine. In this file, I call the upsell.phtml file like this:

<?php echo $this->getChildHtml('upsell_products') ?>

But that doesn't work. If I call it in the view.phtml, it works. But when I call it in the product.info.phtml file, it fails to work.

Here is the code I am using inside the product.info.phtml file:

<dl class="product-collateral">
 <dt class="tab"><span>Test text</span></dt>
 <dd class="tab-container">
  <?php echo $_product->getInfo(); ?>
 </dd>
 <dt class="tab"><span>Test text</span></dt>
 <dd class="tab-container">
  <?php echo $_product->getService(); ?>
 </dd>
 <dt class="tab"><span>Test text</span></dt>
 <dd class="tab-container">
  <?php echo $_product->getInsurance(); ?>
 </dd>
 <dt class="tab"><span>Test text</span></dt>
 <dd class="tab-container">
  <?php echo $_product->getTerms(); ?>
 </dd>
 <?php echo $this->getChildHtml('upsell_products') ?>
</dl>

EXTRA INFO

I did not make this myself, someone else did. I am just here to solve the bug, so there might be missing some information

Try This

            <?php  echo $this->getLayout()->createBlock('catalog/product_list_upsell')->setTemplate('catalog/product/list/upsell.phtml')->toHtml();?>
