Can Attribute Show Certain Words on $0 Attributes?

Zen Cart Version 1.5.1

I am not sure if this going to be simple or more complicated.
What I wanted to do is to have attributes that have $0 to show certain wording.

I wanted attributes to look similar to eMed Hospital Beds site.

Currently, this is how attributes look...

No Bed Rails
Invacare Reduced Gap Full-length Bed Rail [6629]
Invacare Reduced Gap Half-Length Bed Rail [6630]

However, I **do **wanted to be like...

No Bed Rails
Invacare Reduced Gap Full-length Bed Rail [6629] COLOR="#008000"[/COLOR]
Invacare Reduced Gap Half-Length Bed Rail [6630] COLOR="#008000"[/COLOR]

However, I **do not **really want to be like...

No Bed Rails COLOR="#FF0000"[/COLOR]
Invacare Reduced Gap Full-length Bed Rail [6629] (FREE!)
Invacare Reduced Gap Half-Length Bed Rail [6630] (FREE!)

I don't want the word "FREE!" showing up on attribute that add no accessories at all.

I'm not sure how complicated to set that up. I don't think I can do that via admin panel.

to get you going until a better solution comes along

in includes/modules/attributes.php

// normal price

                        if ($new_attributes_price == 0) {

                          $products_options_display_price= '';

                        } else {

                          $products_options_display_price= ATTRIBUTES_PRICE_DELIMITER_PREFIX . $products_options->fields['price_prefix'] .

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

                        }

                      }

                    }

change line to

                          $products_options_display_price= ' (Free !)';

Where YOUR_TEMPLATE is the name of your active template...

Realize that the below solution (provided by bn17311) will apply " (Free!)" to ALL attributes that have a zero price, not just those of any specific category, product, etc...
