Hello,

I thought that this would be an option in forms but it does not look like we can without something custom. 

I'm looking for idea to handle a situation. I have a form that is going to be used to update an email in a SQL DB. I use 2 pieces of data, Last name and ID number for the lookup. The form will then fill in a field with their current email. What I want to happen is that if they typed their id or last name incorrectly, the form would have a message that they mis-typed something. The other thing to consider is that its possible for the lookup to return NULL if they dont have an email on file. Thats why the easy way of adding an error message if the email field is empty wont work. I wish Forms had a feature to give an error if the lookup fails but I don't see anything like that. Any idea of the best way to attack this would be greatly appreciated. Thanks.
