thanks for both replies,
I copied the code into /customer/main/product.tpl
PHP Code:
{if $product.appearance.buy_now_buttons_enabled}
{if $product.forsale ne "B"}
<div class="buttons-row buttons-auto-separator">
{include file="customer/buttons/add_to_cart.tpl" type="input" additional_button_class="main-button"}
to
PHP Code:
{if $product.appearance.buy_now_buttons_enabled}
{if $product.forsale ne "B"}
<div class="buttons-row buttons-auto-separator">
{if $product.taxed_price ne 0}
{include file="buttons/add_to_cart.tpl" style="button" href="javascript: if(FormValidation()) document.orderform.submit();"}
{/if}
This method works well only when there is no product variants. New question now is what template(s) should I edit for those hav variants?
cheers
