Create a box text with secret code to enter.

Hi, it's possible to create a text box that can only accept some secret code, previously communicated through mail for each user?

Thx

I am not entirely sure what you meant about that. But yes, you can create a hidden text box and simply prepopulate it via the URL parameter. Here's a guide about prepopulating URL: https://www.jotform.com/help/71-Prepopulating-Fields-to-Your-JotForm-via-URL-Parameters 

You can also use conditional logic to show/hide different text boxes depending on some rules set: https://www.jotform.com/help/57-Smart-Forms-Using-Conditional-Logic 

We could help you further, but we need to learn more how your process flow works. 

I hope that helps.

Hi, the text box shouldn't be hidden, but must accept only few numbers.

The purpose of this is to create a box that check Unique Validation Code, previously assigned to each user.

Every user must enter his own Code to fill the form, without the right Code isn't possible to complete the form.

Just for example: 

John as the Code 1234
Will as the Code 2345
Karl as the Code 3456

The text box only accept this three Code.

Thx

After that, you can create conditions as you see below:

At that situation, it will work properly.

Here is how it works n my side:
