X-Cart forums - Coding With Product's Extra Fields

Not sure why, but I get nothing. I get the extra fields to pull in fine into product.tpl. What am I not seeing?
products.tpl

Code:

<TD valign="top">

<h1 style="margin: 0px; padding-bottom: 5px;"><FONT class="ProductTitle">{$products[product].product}</FONT></h1>



{* Get the product ID as we loop through the products to be displayed *}



{assign var="productId" value=$products[product].productid}

{php}

global $sql_tbl;



// Get the product id from the smarty var



$productid=$this->get_template_vars('productId');



// Get the rows from the extra_field_values table for this product id



if($productid) {

    $extra_fields = func_query(

      "SELECT productid, fieldid, value as field_value

       FROM $sql_tbl[extra_field_values]

        WHERE productid = $productid"

    );

}

$this->assign("extra_fields",$extra_fields);

{/php} 







{$extra_fields[2].field_value} 



 



{$products[product].descr|truncate:500:"...":true}

products_t.tp

Code:

<TABLE border="0" width="100%" cellpadding="5" cellspacing="1">



{math equation="floor(100/x)" x=$config.Appearance.products_per_row assign="width"}



{section name=product loop=$products}

{assign var="discount" value=0}

{* Get the product ID as we loop through the products to be displayed *}



{assign var="productId" value=$products[product].productid}

{php}

global $sql_tbl;



// Get the product id from the smarty var



$productid=$this->get_template_vars('productId');



// Get the rows from the extra_field_values table for this product id



if($productid) {

    $extra_fields = func_query(

      "SELECT productid, fieldid, value as field_value

       FROM $sql_tbl[extra_field_values]

        WHERE productid = $productid"

    );

}

$this->assign("extra_fields",$extra_fields);

{/php} 

{if %product.index% is div by $config.Appearance.products_per_row}

<TR>

{assign var="cell_counter" value=0}

{/if}



{math equation="x+1" x=$cell_counter assign="cell_counter" }



<TD align="center" valign="top" width="{$width}%" class="DialogBox">



{$products[product].product}




<!-- {$lng.lbl_sku}: {$products[product].productcode}

 -->

{$extra_fields[2].field_value}

{if $active_modules.Special_Offers ne "" and $products[product].have_offers}

{include file="modules/Special_Offers/customer/product_offer_thumb.tpl" product=$products[product]}

{else}

here is the page: http://www.empowermentgroup.com/xcart/home.php?cat=26 The products work fine.

Thanks
