Browser-based form. I want people to fill out an expense form. There is an ExpenseDate field, a Mileage field, and a Mileage Allowance field. If the ExpenseDate is < 1/1/2009 then I need the MileageAllowance field to show Mileage * 0.585 else Mileage * 0.55.
InfoPath doesn't use straightforward if statements. Please help.
