Cognito-forms – Payments installments in Cognito Forms

We are working on releasing support for multi-user organizations, hopefully today or tomorrow, which will allow you to invite other members of your staff to Cognito Forms within a single organizational account.

Also, we have lots of customers using our Zapier integration to push entries from Cognito Forms into Google Sheets or uploaded files into Google Drive. You can learn more about this in our announcement blog post:

I'm a developer with Cognito Forms. Unfortunately, a checkbox can only have two states, checked or unchecked, which equates to true or false in the context of a calculation. However, I do believe you can accomplish your requirement by using the "Radio Buttons" option for the Choice field, without it looking strange or odd. A Choice field does not require a default value therefore you do not need a third option to represent that null state. For a choice field to not have a default selection, the checkbox next to all Choices should be unchecked. I included a couple of screenshots to help explain this configuration. The first one is the configuration for the "Radio Buttons" Choice field and the second is a Yes/No field configured to be visible when the Choice field value is "Yes". I hope this helps. Hopefully, I am not misunderstanding your requirement.
