Hello…

```
I have an order form that I've created that collects personal information and such... now, I have set amount for the product ($69.95) but at this point they can only buy one at a time... the question is, how can i use a dropdown or input box as the quantity and have the for calculate the amount? For example, the price is $69.95 and the customer would like to buy 3 sets... $69.95 X 3... how can I do that calculation in the form?
