How to calculate a discount using Form calculation widget?

Hi. I am trying to build a quote form and offer a discount to the customer after completing the quote Is there a way I cn do this using the form calculation widget. i.e, a total is generated using the calculator, but i want the customer to be able to choose one of our offers and have the calculator automatically deduct it from the original generated amount. Thanks.

I'm not sure how the discount should be calculated.

You can use the field you added for calculating it:

And simply deduct the price. But, what defines the discount, if you can give us an example, we could certainly help you?

We'll wait for your response.

Thank you!

Thanks for your reply.

I want to offer a 10% discount to those who pay a 20% deposit when booking, and a 20% discount when paying in full when booking which will be 20% of the price calculated in the first box, s I wanted the second box to take the quote price, discount it by either offer the customer chooses 

Hope my explanation makes sense.

Thank you for additional information. 

I understand what you're trying to do, I just wasn't sure how they choose if they will pay full or deposit.

So I decided to create something like this:

1) I added three short text fields for calculation purposes (those can be hidden) and one radio button:

2) Then I created these conditions:

Those calculations can be passed to Payment field later for processing.

Could that work for you?
