    How can I make a part of a product fee required?

    Asked by destonmarketing on November 20, 2014 at 01:38 PM

    I have several packages with my business. One of them have a setup fee. Is there a way I can make that fee required IF they choose that product. For example, I have a $49.00 setup fee and then charge $0.25/min. If they choose this option I would like the $49.00 setup fee to be required and then they put in the quantity of minutes. If they choose another product, then this fee wouldn't show up.
