Group by currency. Then use a running total to get your amounts, where you say change by group {currency} and reset by group {currency}

If you really want it to say it like that, you could play around a little bit. You should place the running total in the group footer. Then you could suppress the group header and detail section.

If you really want the text to say "TOTAL (CURRENCY) (AMOUNT)", then you could create a little text block with the text "TOTAL (", then your currency field, the text ") " and then the running total.

Finally, if you don't want to show currencies that have a total value of 0, you could suppress your group footer <= 0.
