I am trying to find a solution to this. I am selling books as part of the event registration. I want the user to be able to purchase more than 1 books. I created a field for the option to buy the book, and the option for paperback or hardcover. But, I can't figure out a way for the user to input the quantity and then have the fee calculation add on the to event fee. Any suggestions?
P.S. The only way I was able to make it work is that if I created a separate drop-down field with pre-configured numbers.
You were on the right track. You must have a selection field to calculate any prices, so a dropdown would be the route to go. There is no method currently of having a regular input field that can calculate anything. Thanks.
