Validation Rules for Check Box

Hi, I have a created a check box field named "Is Credited". I want to write a validation rule "Is Credited is not true" so I used NOT(Is_Credited__c) but it seems to be wrong. Can anyone help me with the right syntax?

The formula syntax is correct. You can use the debug logs to verify the value that is being passed during the validation rule and find why the validation rule is not working for you.

Is_Credited__c <> true

Try it!
