How to clear value of admin only field?

The problem with this it that after submit button is pressed the passcode is recorded on the "Admin-only" field and when the respondent open the form the submit button will be visivle.

I tryed clearing the "Admin-only" field after submited has been pressed but I had no lucky.

Any clues? my best.

Hello certipma,

I am not sure if I have understood your question correctly. Do you mean to say that you want to clear the "Admin-only" field after the form is submitted?

Unfortunately it is currently not possible to automatically clear the value of admin-only filed as if you add condition to clear it, the another condition to show the other form field to approve the submission. The only option is to edit your submission from your form's submission page and manually delete it. 

Thank you!
