Imagine this:
We have a list of products.
Each product can have an add-on.
Each product can have a duration (starts at 1-1/2 hours, goes up in 1/2-hour increments).
The price is a function of the base product, the number of add-ons, and the duration. Yow! Can I do this with Gravity forms?
Here's a quick example of the kinds of values I'd like to get (prices simplified to show concept):
Basic petting zoo, 1-1/2 hours (shortest duration): $200
Petting zoo + 1 pony, 1-1/2 hours: $260 (adding ponies adds $60 per pony for the first 1-1/2 hours)
Basic petting zoo, 2 hours: $250
Petting zoo + 1 pony, 2 hours: $270 (adding ponies *and* time is more complicated)
The formula is:
B = base price, 1-1/2 hour party
N = number of ponies
T = Extra time, in half-hour increments
Price = B + N*$60 + T*$50 + T*N*$10
I.e., each pony adds $10 per half hour of additional time.
