Going from inthepink's code I did this...

create a tpl. file in buttons called continue_shopping.tpl

add the following code to it...

{* source: http://forum.x-cart.com/viewtopic.php?t=1124 *}
{if $goto eq "product" and $last_productid neq ""} 
{assign var="href" value="`$WebDir`product.php?productid=`$last_productid`"} 
{elseif $last_cat neq ""} 
{assign var="href" value="`$WebDir`home.php?cat=`$last_cat`"} 
{else} 
{assign var="href" value="`$http_location`"} 
{/if} 

{include file="buttons/button.tpl" 
button_title="Continue Shopping" style="button" href="$href"}

add to config.php....

x_session_register("last_cat"); 
x_session_register("last_productid"); 

if($HTTP_GET_VARS['cat'] != "") 
{ 
   $last_cat = $cat; 
} 

if($HTTP_GET_VARS['productid'] != "") 
{    
   $last_productid = $productid; 
} 

$smarty->assign("last_productid", $last_productid); 
$smarty->assign("last_cat", $last_cat); 

You can then use....

{include file="buttons/continue_shopping.tpl"}

whereever you like to give you a continue shopping button. I've got it next to the checkout button and also below 'Your shopping cart is empty'

sweet!
