Right Click on the control, and make a reference. Right Click on the Reference constant and make it a control. Move this control to the subvi, it is a control of the correct reference type to invoke methods from a subvi.

A ""An input parameter is invalid." error could be caused by passing a reference that has gone invalid because the entity that created the reference has gone idle (could have been edited).
Does the original creator of the reference stay active?

Sorry I assumed from the question that this was a reference to a control on a caller vi which stays opened so no reference managerment is needed.
