Im not sure what it is your trying to do but looking at the code you have for order_data_provider.tpl it looks as if the code is incomplete.

The section code does not get closed

This is the code form order_data.tpl in its complete form.

{section name=prod_num loop=$products}
{$lng.lbl_sku}:        {$products[prod_num].productcode}
{$lng.lbl_product}:    {$products[prod_num].product}
{$lng.lbl_quantity}:   {$products[prod_num].amount}
{if $products[prod_num].product_options ne ""}
{$lng.lbl_selected_options}:
  {$products[prod_num].product_options|replace:"\n":"\n  "}
{/if}
{$lng.lbl_item_price}: {include file="currency.tpl" value=$products[prod_num].price}


{/section}
