Attributes Base Price next to default attribute

[perfumbg]

I found something on line 159 in modules/attributes.php

                          $currencies->display_price($new_attributes_price , zen_get_tax_rate($product_info->fields['products_tax_class_id'])) . ATTRIBUTES_PRICE_DELIMITER_SUFFIX; 

wich i edited like that

                          $currencies->display_price(($new_attributes_price + $products_actual_price), zen_get_tax_rate($product_info->fields['products_tax_class_id'])) . ATTRIBUTES_PRICE_DELIMITER_SUFFIX; 

but the $products_actual_price from functions_prices.php does not display any value and I can't think of other way.

If someone have made sucsesful changes please help here :)

Thanks
