Prohibit certain values?

Hello,  Is there a way throw a error message if user submits certain values in certain fields?  For example, if user types "Christine" in the name field, then return an error message saying "Sorry, Christine is not unable to register because due date has past for him/her."

Thank you.

1. You can do that by adding a text field with the error message

You can add also a Date/Time field, and set the default date (click on Default Time button) , while disabling the Time itsel (so it won't show hours and minutes)

2. Then adding a conditional logic with 2 rules (if you will , you can add the rule for the Date)

If NAME field is EQUAL TO  Christine

If DATE field AFTER 'today'  (you can vary this

THEN SHOW  "Sorry, Christine..."

Otherwise, only the first rule would be enough.

Let us know should you have more questions on regards to this.

I forgot to post my test form

if you put "Christine" or a date later than 'today'  , the message will appear.
