how to enforce user to fill in either one of the text fields before submit

Hello ​@angeliho,  

Welcome to the Docusign Community! Thanks for posting your question here. I understand you want to mandate only one text field for your signer. We’re here to help!

To clarify, we cannot restrict one text field based on the other. To fix this, use a Radio Button group as a trigger. This forces the signer to pick one option, which dynamically displays and requires the correct text field.

To set this up, please refer to the following steps:

1. Insert Radio Buttons: Place a Radio Button field with two choices (e.g., "Option 1" and "Option 2").
2. Configure Text Field 1: Insert the first numerical field and mark it Required.
3. Configure Text Field 2: Insert the second numerical field and mark it Required.
4. Create Conditional Rules: Select the Radio Button field to build your logic.
5. Rule 1: If Option 1 is selected, Show Text Field 1.
6. Rule 2: If Option 2 is selected, Show Text Field 2.

Docusign only mandates fields that are visible on the screen, allowing users to submit without errors. You can find deeper technical details in the DocuSign Conditional Field Guide.

I hope this helps! Let me know if you have any questions.

Sorry, we do not want to add radio button to this docusign template.

We need to keep PDF version and docusign version the same to avoid client confusion.

This is a very common business requirement, and I just surprised it cannot be achieve without adding non-necessary elements to the form

Hello ​@angeliho, 

Thank you for your feedback. We understand your requirement to keep the PDF and Docusign versions identical and not use the suggested workaround for your envelope.

We currently do not support the functionality or conditional rules required to hide text fields in this manner.

However, we value your suggestion and would appreciate it if you could post this on our Docusign Community Idea Channel. Our internal engineers regularly review these posts to plan future product innovations.

Thank you for helping us improve our platform. Please let us know if you have any other concerns. We’ll do our best to help!
