We have a PDF template where we're calculating the amount for a specific line but I'm having trouble getting that amount to format properly for different currencies. In our template, if we simply display

${line.amount}

, it's formatted properly for the given currency as expected. The amount that's calculated within the template simply displays as a number when we output

${groupTotals[item.lineuniquekey]}

. I've tried formatting

?string.currency

but this always formats with a $ with comma separator and . decimal separator. I've tried formatting `?string[",0##.00"]
