Hi everyone!
I'm new to the forum and to javascript.

I have to make a simple fillable form pdf with a shopping cart, and I'd like to have some help.
I have a column which indicates the prices, and near each price there's a checkbox. When the client checks a checkbox, I want it to retain a specific numerical value (i.e. the cost of the corresponding service).

Then, at the end of the form, there's one cell in which I'd like to sum up all the numerical values of the checked boxes.

I really have no clue!

Thank you,

Luca
