*[Done v1.6.0] Missing 'echo' in tpl_product_info_noproduct.php

In /includes/templates/template_default/templates/tpl_product_info_noproduct.php there's a missing echo that causes the "Continue" button not to be displayed:

<div class="buttonRow back"><?php echo zen_back_link() . zen_image_button(BUTTON_IMAGE_CONTINUE, BUTTON_CONTINUE_ALT) . '</a>'; ?></div>

It turns out that there are a couple more issues with this script. For each of the new/featured/special products modules, it's calling the module instead of the template so that nothing is ever output to the screen. Here's an entire update, based on the v1.5.1 version:

<?php

?>
<div class="centerColumn" id="productInfoNoProduct">

<div id="productInfoNoProductMainContent" class="content"><?php echo TEXT_PRODUCT_NOT_FOUND; ?></div>

<div class="buttonRow back"><?php echo zen_back_link() . zen_image_button(BUTTON_IMAGE_CONTINUE, BUTTON_CONTINUE_ALT) . '</a>'; ?></div>

<?php

Thanks lat9. This was a timesaver.
