How can I set price amounts and also give an option to input their own amount into the same form

Right now I have checkboxes with different donation amounts connected to the payment section.

Is there any way I can have an "other amount" box so they can input their own amount?

I want it to all be on the same page with the same payment section.

Thanks,

Sarah

Unfortunately, you cannot set the payment integration to have a list of products then have a custom amount input.

However, this can be done by manually recreating the product list using the default form fields, we will then use the form calculation widget to fetch the value and pass it on the payment wizard. Here are the steps:

1. First, recreate the product list using the radio button field. Make sure to change the options in it.

2. After that, click the properties of the radio button field. Add the values in the Calculation value, we want to give each option a real value. We will also enable the "Allow Other" so that your users can input their own donation amount. Here's a separate guide on how to assign a calculation value: http://www.jotform.com/help/301-How-to-Assign-Calculation-Value. 

3. After that, we want to fetch the value of the option selected by using the form calculation widget.

4. Use the "Add filed" button and the radio field here.

5. Now how to pass the value on the form calculation to the payment integration? You can do that by following this guide: http://www.jotform.com/help/275-How-to-pass-a-calculation-to-a-payment-field 

Here's a sample form that I did, I cloned your form for testing and demo purposes: http://form.jotformpro.com/form/52025521277954. 

I hope that helps.
