Show nothing if there isn't price or list price

Hi,

I’ve create a template:

Price: %PRICE%

List Price: %LIST_PRICE%

if the product is not avaliable or there isn’t the %LIST_PRICE% shown in Amazon site I would like that anything is shown.

Insted the result is:

Price: –
List Price: –

How can I show nothing?

Thanks
Dyana
