[Total Supply]

And i'm guessing the statement in related_products should be:
<font class="ProductPrice">{$lng.lbl_our_price}: {include file="currency.tpl" value=$product_links[cat_num].taxes}</font><font class="MarketPrice">{include file="customer/main/alter_currency_value.tpl" alter_currency_value=$product_links[cat_num].taxes}</font>

At the moment I get "$Array"
