Have you ever seen
www.apple.com/store?
And if you noticed when you choose G5 for example... you
select the kind of MAC and then you can customize it, add memory,
another hard drive, bigger monitor... etc.
Well, each time you select from the menu to customize the
computer, the price updates.
I am making a similar thing. BUT ITS NOT A SHOPPING CART!!!..
I want the visitors to be able to make their own custom package of
"wedding videography"... the advantage? They see in real time, how
much it will cost them. Then when they're ready, they send it as a
"Request for Services" to the videographers.
The vidographers in turn, get an email and see a request, and
can contact their potential client and discuss what they've chosen.
That's the idea. Now in that process, I know everything
except the part that UPDATES THE PRICE in real time, as if it was a
cart.
How do I do that?
