[mv] Still displaying discount...

I need to display the order discount amount, and have been
using the code below to do it:

>No; but you could create one by taking advantage of the [discount]
>tag sharing memory space with [calc]....
>
>        [discount ENTIRE_ORDER]
>                $original = $s;
>                $discounted = $s - 5.00;
>                $difference = $original - $discounted;
>                return $discounted;
>        [/discount]
>
>        Total cost is [total-cost].
>
>        You save [currency]
>                                [calc]
>                                        return $difference;
>                                [/calc]
>                        [/currency].

Works fine, but what about displaying it on the email report, report.html?
Thats not HTML so you can't call [total-cost] inside <!-- HTML comments -->.

How can I display the discount amount on this page? I've had zero
luck setting variables with [set discount_amount]anything[/set], I
can never get a variable to set. Otherwise, maybe, somehow, I
could store this discount amount in a variable and then use that
where I need discount amount?

Thanks,
Ryan
