is it possible to not print the dollar sign when printing the invoice total?

See the functions available here: https://netsuite.custhelp.com/app/answers/detail/a_id/26500#subsect_156624108232 Specifically, you could try

${nsformat_number(record.total)}

I just used ?string?replace("$","")

Thank you for sharing that article @scottvonduhn. I didn't know it existed.
