As I type this I'm not sure this is going to be possible - or at least the right way to go about this.
I'm rebuilding an existing form, which has a number of fields (with prices) as drop-downs.
This will give you an idea;
The first drop-down has 3x other options - all with different prices.
The second drop-down goes all the way up to 10 nights - so that's a lot of possible combinations.
The second drop-down only appears once the user has selected an option from the first.
There is one more field using the 2x drop-down scenario.
5x others that only make use of the one drop-down (with prices).
The end scenario is that all these get added up (somehow?!) & the user then gets directed to PayPal to purchase whatever options they have selected.
Somewhat complex (for me at least) so any advice would be very much appreciated!
