I am setting up a webform for online ordering of trademarks. Short background: Trademarks are organized in 45 classes, each comes along with a "general class description", i.e.
Advertising; business management; business administration; office functions.
Now some people may want to only register their trademark for lets say "Advertising" while others may want to add more specific words.
Depending on how many classes the user checks positive, the official trademark fee increases in the following way: 1-3 classes cost 300,00 €, every additional class in 100,00 € extra, i.e. 5 Classes = 500,00 € or 2 Classes = 300,00 €.
1. Question: Is it possible to create user-editable text fields with non disappearing Placeholder text (Placeholder=General class Description)? Which function do you recommend?
Parallel the amount of positive checked classes must to be connected to the official fee costs. I want to display the individual costs inside the ordering process, so Users know the live-calculated costs prior to checkout.
2. Question: Any suggestions on how to define a formula regarding this connection?
Looking forward to your answers. Cheers
