Hi Danilo,

I didn't know the answer until two days ago where I had to display the 
total cost on the receipt (which is inclusive of tax) but show what 
proportion was actually tax.

<tr>
    <td colspan=3>
        &nbsp;
    </td>
    <td>
        TOTAL GST ON INVOICE
    </td>
    <td align=right>
[calc]
sub subtotalgst {
     my($subtotal,$x) = @_;
$subtotalnumber=substr($subtotal,1,20);
$subtotalgst=$subtotalnumber*(1-0.909090909);
    return '$'.sprintf("%.2f",$subtotalgst);
    }
[/calc]
        [calc]subtotalgst('[total-cost]')[/calc]

    </td>
</tr>

I think the answer to your question is that the subroutine subtotalgst 
uses the [total-cost] already in use on the receipt.

Thats a good idea by the way. I have included insurance in the shipping 
calculation which is a modification of the ups_query tag.

I may actually display insurance separately if I can find a logical way,
