How to store multiple user information into single custom data object

Summary:

I have created a form in Eloqua to capture user information, and I want to store multiple users’ data in a single Custom Data Object (CDO). I attempted this, but only the first user’s information is being stored, while the second user’s data is not.

Content (please ensure you mask any confidential information):

In the form processing step, I used “Update Custom Data Object – With Form Data” to store the submitted information into the Custom Data Object (CDO).
