Right now I have a conditional code field value where if users enter the correct field value, it will display additional fields.
The values are a data set from a txt file. I was wondering if it was possible to disallow a value once it’s been submitted once.
For example if we had the following codes in the txt file:
When someone submits a form with the code 123 then that code is not allowed to be entered again.
We want to prevent duplicate entries from happening if possible.
