I need to develop a form for my client where a discount is applied when two or more products are purchased. The client sells professional workshops. If the attendee books for two or more workshops, a discounts shoud be applied. If only one workshop is booked, no discount is applied.
Please see the demo I have online here: http://www.psychworkshops.co.za/cpd-workshops-and-training/new-form-test-page/
In Bloemfontein, there will be three workshops. If they book for two workshops, a discount should apply.
However, in Johannesburg, there wil be a lot of workshops (7-10). If two or more are booked for that city, a discount should also apply. Again though, if only one workshop is booked, no discount should apply. (I've not got any courses up for the other cities, just Bleomfontein for now.
Is there a way to do this, or can you suggest a workaround to get it to work?
