So occasionally I blow up my easypopulate.php import and create a bunch of bogus categories by accident that I delete out so I want to have my delete icon open in a new window. I was trying to simply add the &target="_blank" to the link as seen below, but it only loads as &target=

any idea why? I can't seem to escape? the double quote maybe? I tried slashes, concatenating, etc. I think I'm just too much of a n00b.

admin/includes/modules/category_product_listing.php

Code:
<?php echo '<a href="' . zen_href_link(FILENAME_CATEGORIES, 'cPath=' . $cPath . '&cID=' . $categories->fields['categories_id'] . '&action=delete_category') . '&target="_blank">' . zen_image(DIR_WS_IMAGES . 'icon_delete.gif', ICON_DELETE) . '</a>'; ?>
