    Conditional Logic: Adjust price of product with a drop-down

    Asked by Eric Hicks  on June 22, 2016 at 10:53 AM

    Hi, I'm a web developer considering using jotform for a client website.  We have a particular need for a drop-down that will affect the price of the product.  The form we will create will be hooked up to authorize.net, but the product price is variable, depending on which selection the user picks from a drop-down.

    Is this possible with jotform?

    Thank you,

    Yes it is possible to achieve that using Conditional Logics. I've made a sample form using a condition that dynamically changes the value of the textbox (Total) based on the option selected on the dropdown menu (Quantity). If that's what you're aiming to achieve, just clone my form so you can tinker around with the conditions I have setup.

    What I did is just a basic condition that updates the textbox field. Keep in mind you may also do simple to complex math calculations using conditions so have fun.
