Subject Re: Currency Formatting

Thanks Chris. The reason I use this method in my iterators is there are a 
few places where I use nested iterators so the # notation is the only way to 
access the current iterator but also the parent iterator.

This specific iterator is not nested so I have changed it for learning and 
trial sake and it fails with the line

<span class="product-price"><s:text name="format.currency"><s:param 
value="price"/></s:text></span>

I can put

<span class="product-price"><s:property value="price"/></span>

and it displays the value fine.

Chris
