I have created a custom edit step (LabVIEW VI) in which the user can create a Local, StationGlobal or FileGlobal variable to store some data in. When the user hits the "add" button an event is triggered and the variable is created. I want the user to be able to hit the "remove" button and cause an event to be triggered that removes the variable. Is this possible, or do I need to specify that the user removes the variable manually? The front panel and add portion of the block diagram is attached.
