I've tried to modifying the code in the middle to display the variant price adjustment. But no luck. I did successfully add an if statement to identify a variant, but I can't seem to get the correct variable to display the variant price. Actually I'll need to calulate (Variant Price - Product Base Price) to get the variant's additional cost over the base price.
From: skin1/modules/Prodcut_Options/customer_options.tpl
Code:
{if $v.is_modifier eq 'T'}
<input id="po{$v.classid}" type="text" name="{$poname}" value="{$v.default}">
{else}
<select id="po{$v.classid}" name="{$poname}"{if $disable} disabled{/if} onChange="javascript: check_options();">
{foreach from=$v.options item=o}
<option value="{$o.optionid}"{if $o.selected eq 'y'} selected{/if}>{$o.option_name}
{if $v.is_modifier eq 'Y' && $o.price_modifier ne 0}
(
{if $o.modifier_type ne '%'}
{include file="currency.tpl" value=$o.price_modifier display_sign=1}
{else}
{$o.price_modifier}%
{/if}
)
{/if}
{else}{$o.price_modifier}%{/if}){/if}</option>
{/foreach}
</select>
{/if}
