Prevent certain values in fields

I want to specify invalid values in a field. e.g. don’t allow to submit the form if the value is equal to any of banned values. is it possible to do that?

Thank you for contacting us.
Depending on your exact scenario, there are a few options you can employ, such as adding instructions or a prefilled value to your field, as well as editing the expected format of the field (numeric, alpha), not allowing duplicate values or matching another field’s value. According to what you set, the form user will not be able to submit the form unless the conditions are set. Here is a short video tutorial on how to prevent certain values in fields.
If you have something more specific in mind, such as having an exact word not accepted on the form, I recommend you use a field rule where you can type the values that are not accepted and hide the Submit button if the condition is not met. Here is a short video tutorial on how to ban specific values from fields.
If you have any other questions or concerns about this or anything else, do not hesitate to reach out and we’ll be happy to assist.
