Also placed this code into shopcart/skin1/customer/main/buy_now.tpl
So it shows in normal mode without going to the details section.
Just add the code between {* funkydunk notify mod *} and {* end of funkydunk notify mod *}
Code:
<TD width="20%" nowrap>
{if $config.General.unlimited_products ne "Y" and ($product.avail le 0 or $product.avail lt $product.min_amount)}
{$lng.txt_out_of_stock}
{* funkydunk notify mod *}
{if $active_modules.stock_notify ne "0"}
{ include file="modules/stock_notify/notifyme.tpl" product=$product}
{/if}
{* end of funkydunk notify mod *}
{else}
{if $config.General.unlimited_products eq "Y"}
{math equation="x+1" assign="mq" x=$config.Appearance.max_select_quantity}
{else}
