Question : Date Formula deducting today's date from date field

I keep getting "the ) is missing" when running the formula below

What the formula is supposed to do is deduct today's date from {SALES_ORDER_HEADER.REQD_DATE} to show days late for the order

Any ideas?

1:	Date (mm,dd,yy) - {SALES_ORDER_HEADER.REQD_DATE}

Answer : Date Formula deducting today's date from date field

Currentdate - {SALES_ORDER_HEADER.REQD_DATE}
