When creating the Detail page, you should deselect the option to include the delete button if it will be used as a public add to cart page.
The add to cart button that is added, is really just a place holder.
you should delete the following code from the detail page:
<form class="DetailsPage Cool_Default" id="Results_Cool_Default" method="post" action="<?php echo (htmlentities($_SERVER["PHP_SELF"], ENT_QUOTES)); ?>">
<input type="submit" value="Add To Cart" class="formButton Cool" id="Cool" name="Cool" />
</form>
then add the eCart add to cart button behavior.
