The 'edit validation' rule has the ability to select the boolean expession '[expression evaluates to true]' but the opposite does not exist. I am making a rule if a value populates in a pagelist's certain property then it hides a particular field. I am having difficulties since visibility may change depending on which value has been populated in the pagelist so I really need the opposite of the '[expression evaluates to true]'. Can someone enlighten me?

Are you talking about the Edit Validate rule? If not can you share some screen shot of your rule where you are trying to perform this validation. If you are trying it in Edit Validate rule then its just a piece of Java code that you can write to perform your validation.
