Validate field values - if a future date is entered condition

Summary:

We have users who when the enter a sickness record the "userMode" : "ADMIN"

As we have set against the absence type Administrators can enter future dated absences they are able to perform the action.

However we want to restrict users of this role from creating a future dated absence.

Therefore in visual builder studio trying to create a validate field values rule.

Have entered the first two conditions but what can enter in the third - which should be something like if the start date is in the future i.e. greater than sysdate.

Also need this rule to fire and produce the message inline with the start date field before you click the submit button if possible.
