Application form that can multiply the quantity to the value of product purchased

Boa noite, preciso criar um formulario de pedido que vá multiplicando o valor de cada item pela quantidade comprada e depois faça uma somatório de todos os itens no valor total.

Exisite alguma ferramenta para isso?

Hello,

If what you want is to create a list of products which you can have an option to set a price for each and set a quantity, you can add an element under Payment Tools.   If you do not want any payment gateway service, simply choose the Purchase Order at the bottom.

You can get a more detailed explanation on how to add products and quantity from this user guide: https://www.jotform.com/help/165-Setting-Up-Your-First-Order-Form

If you have more questions, please do let us know.

Thanks.
