Like others, I was having issues with the mod only showing the last viewed product, not the last 4. I'm guessing it has something to do with the tabbed product menu on my page. So I moved the code for product.tpl to the top of that page instead of the bottom.
I then moved the include file from post #42 right below this on product.tpl, as opposed to including it in home.tpl.
So the top of my product.tpl file looks like this:
Code:
<script type="text/javascript">
prodImage='<img src="{$product.tmbn_url}"/>';
prodName='<{$product.product}>';
var p0=('<br/><a href="'+document.URL+'">'+prodImage+'<br/>{$product.product}</a><br/>${$product.taxed_price}<br/>');
</script>
{include file="customer/main/recently_viewed_2.tpl"}
Seems to be working great so far. I'm using the mod on the left.
