Adding “monetary” values from multiple elements

[mdez]

Hi, I’m creating a form with multiple elements, similar to an order cart but a bit more custom. I’d like to know how to do addition from the different elements.

For example:
Checkbox1 is $15; Checkbox2 is $30

If only Checkbox1 is selected then the textfield will display $15. If both are selected or active then textfield will display the total $45

Please help. Thank you so much 🙂
