I have task with two buttons (Reviewed and Cancel).  Before the user can cancel the task, they need to provide a reason for canceling.  My goal is to hide only the Cancel button until they click Yes in a radio button selection, Do you want to cancel this task?  I'm having trouble trying to key in only the Cancel button since both have the action of Submit when I inspect the element.  Is there a way to hide a button based on value="Cancel" to differentiate between the the Reviewed and Cancel button?
