Base price question, how it works

Here is a code below from tpl_product_info_display.php file and I have a question about it.
**<?php // base price if ($show_onetime_charges_description == 'true') { $one_time = '<span >' . TEXT_ONETIME_CHARGE_SYMBOL . TEXT_ONETIME_CHARGE_DESCRIPTION . '</span><br />'; } else { $one_time = ''; } echo $one_time . ((zen_has_product_attributes_values((int)$_GET['products_id']) and $flag_show_product_info_starting_at == 1) ? TEXT_BASE_PRICE : '') . zen_get_products_display_price((int)$_GET['products_id']); ?>
**

When the price is set and attributes are added it reads second part of the code above:
** echo $one_time . ((zen_has_product_attributes_values((int)$_GET['products_id']) and $flag_show_product_info_starting_at == 1) ? TEXT_BASE_PRICE : '') . zen_get_products_display_price((int)$_GET['products_id']);**
and accordingly shows TEXT_BASE_PRICE text in the listing

If there is no attribute set in the listing it reads the first part of the code and exactly this part:
} else {
$one_time = '';
}
so the listing has only price with no words.

And I need it to read this code part only:
// base price
if ($show_onetime_charges_description == 'true') {
$one_time = '<span >' . TEXT_ONETIME_CHARGE_SYMBOL . TEXT_ONETIME_CHARGE_DESCRIPTION . '</span><br />';

so the listing would show TEXT_ONETIME_CHARGE_SYMBOL and TEXT_ONETIME_CHARGE_DESCRIPTION text in the listing

I hope I explained it clear. If there any switch in admin to make this code work?

Thank you in advance

You have misidentified the code sections: the if($show_onetime_charges_description == 'true') selects between the two $one_time = lines, based on the value of that variable. The variable is set automatically in /includes/modules/attributes.php, line 131, presumably based on whether the product has attributes.

The echo $one_time . line is always processed.
