Formula / Calculation Help


Some of our invoices have tax, some do not so I'm trying to make it so that a "Yes" checkbox named "Taxable" will allow a field called "Tax" to calculate taxas follows:


If ( not  IsEmpty (Taxable)   (Subtotal - Discount_Total) - (Subtotal - Discount_Total) * .625



The latter part of the equation (in italics) already works without the checkbox, I'm just not sure how to make it so that the equation functions only when the box is checked... I'm just not familiar enough with this yet =/


any help is much appreciated!
