I'm seeking a way to create an "either/or" option that allows users to either upload a photo or take one, but not both. I'm struggling to get the logic to function correctly.

Answer:

You can provide users with the option to either upload a copy of their driving license or take a photo of it.
To implement this, you can add a "Single Choice" element with the question "How would you like to provide your driving license details?" and include two options: "Upload a copy of your driving license" and "Take a photo of your driving license".
Depending on the user's selection, you can then use conditions to display the relevant fields to the user. For example, if the user selects "Upload a copy of driving license", you can show the upload field to the users, and similarly for the other option.
