Hello, how i can make something simillar : if i change the radio button it should change the nested fields any ideas ? what i must search for .
Firstly, welcome to the forums.
While we are primarily here to help people with their Free Code Camp progress, we are open to people on other paths, too. Some of what you are asking is pretty trivial in the Free Code Camp context, so you might find that if you’re not getting the instruction and material you need in your current studies, the FCC curriculum will really help you get started. You can find the curriculum at https://www.freecodecamp.org/learn.
With your current questions, we don’t have enough context to know what you already know or don’t know, so it is impossible to guide you without just telling you the answer (which we won’t do).
It is pretty typical on here for people to share a codepen / repl.it / jsfiddle example of what they have tried so that anyone helping has more of an idea of what help is actually helpful.
Please provide some example of what you’ve tried and I’m sure you’ll get more help.
Happy coding 
JavaScript, I would say…
How far are you in your studies?
i learn jquery, not too much, any guide ?
hint: event listeners
try to search about how to do it on your own

Thank you , so helpful
I have a user form that has two sets of radio button on it. The first set is a group of 14 while the second set is a group of 4. I am looking to have the user select one of each group and submit. While the information is pulled from 8 cells across 2 or possibly 3 sheets. From there I want it to average those cells and post the result in another specific cell on a specific sheet https://trackeasy.fun/usps/ https://showbox.tools/.
I’m not even sure where to start with this one.
