it is in customer/main/product.tpl
here is the head of product.tpl up to the tag instance
Code:
{* $Id: product.tpl,v 1.78.2.4 2004/02/27 13:47:00 mclap Exp $ *}
{include file="check_product_options_js.tpl"}
{if $product.product_type eq "C"}
{include file="modules/Product_Configurator/pconf_customer_product.tpl"}
{else}
{capture name=dialog}
<table border=0 width=100% border=1>
<form name=orderform method=post action="cart.php?mode=add" OnSubmit="javascript:if (!FormValidation()) return false">
<tr>
<td valign=top align=left rowspan=2 width=100>
{include file="product_thumbnail.tpl" productid=$product.productid image_x=$product.image_x image_y=$product.image_y product=$product.product tmbn_url=$product.tmbn_url}
{section name=product loop=$products}
{$products[product].param00}
{/section}</td>
<td valign=top>
{$product.descr}
an example page resides here:
http://www.sharpsusa.com/store/customer/product.php?productid=16133
if the code was working under the image would be a text entry (param00)
thanks for the help on this..
