Form field verification

I want to add a short text question at the end of the form.

And need to check against the input like a password.

If the form filler doesn't input it correctly, they cannot submit the form.

Any suggestion to achieve this? Thanks.

How about password-protecting the form itself? Here's a guide for that: https://www.jotform.com/help/579-how-to-password-protect-a-form/

The user cannot open or view the form unless the correct password you set.

I don't want to hide the whole form from password.

I want an option only available to admin. Then asking form filler to fill password on that option. If they cannot enter the correct password, they cannot proceed with that option.

Alright, then you can use this method: https://www.jotform.com/help/316-how-to-show-or-hide-fields-base-on-users-answer

Use the short text field entry as the criteria. And if your "password" doesn't match with that entry, then the admin fields will remain hidden. Here's an example condition:

Here's a demo form: https://form.jotform.com/213052971961053

Please use "opensesame" as the passcode.

But can still submit the form without having the password correct

Actually, I want to hide the payment and submit the form if filler can enter password correctly. If not they must complete the payment to submit.

Greetings,

Kindly share the form URL so we can have a look at it and see if what you are trying to achieve is possible.

Looking forward to your reply.

Thanks
