Discount Options and Add Option of 50% to Total Price

Hello,

We want to do a relative simple thing. We sell Events and we want to offer following combinations:

1.- CHOOSE AN EVENT:

o Event A = 100 EUR
o Event B = 120 EUR

There should be a discount if customer choose Event A + Event B (In this case 200 EUR, 20€ discount)

2.- PAYING TOTAL AMOUNT NOW or MAKE A RESERVATION?

(a) I Pay Total Now. Total = (Event A or Event B or Event A+B - Discount)
(b) I Pay 50% Reservation Now. Total = (Event A or Event B or Event A+B) / 2

I don't know:

3.- how to parse choices from Optión 1 to (a) or (b)
4.- how to parse (a) or (b) to be the total Price.

"... This form field should do exactly what you want. It should calculate what 50% of the total is and subtract it from the current total. "

OK understood and applied the first discount.

But how do I Calculate the 50% of total in the Calculation form? I don't see "Total" in Allowable form fields when trying to insert that Tag in Calculations.

I guess is done in a different way?

OK.

I got it.

I do it setting a "-" at the beggining of the calculation. And to include the discount (this was the point I didn't understand) I added the Product Discount Field (Price) to the sume and put everything between Brackets then I divide it by 2 so that I get 50% of total as negative number and get 50% discounted for the total.

Thanks a lot..!
