Product List: How to conditionally populate a specific product's quantity using an answer from previous field?

Hi Sarah,

Thanks for reaching out to JotForm Support. I'm sorry you're having trouble with your conditions. Unfortunately, it's not possible to conditionally copy a field value to a specific product's quantity. You may consider using a Form Calculation widget and use User Defined amount in PayPal to automatically capture the amount based on the number of attendees entered. Let me show you how to do that:

• Add a Form Calculation Widget to your form and set the calculation to Number of attendees * 2. You can opt to hide this so the users won't see two prices. One in the widget in another in PayPal field.
• Change the PayPal's Payment Type to User defined amount and select the Calculation widget in the Get Price From field.

That's it. Here's what it should look like afterward:

Here's also a cloned version of your form that you can test.

Keep us updated and let us know if you need any more help.
