Calculation based on user input

I am creating a form that will be similar to how you can manage a product’s price based on the selected variants and it will automatically calculate the price. So, if someone selects a specific input then an additional fee will be added to the total price.

Essentially, I want to do something similar to this: https://futurevisionweb.wixsite.com/greagoriascleaning/booking

Please let me know how can I do this?

Is there a tutorial someone can point me to?

Hi Brett.

Please take a look at the following article: Velo Tutorial: Adding Custom Interactivity with Events | Help Center | Wix.com

How do you adjust this to calculate price and add it to the cart? It shows only for simple interactivity such as showing and hiding items, but not the price calculation. Could you include the code to exactly how it should look so we can then customize it to our page?
