Pass a blank value in Action Button

[PlanningDev]

Does anyone know how to pass a blank value through an action button to a worksheet cell?

Conceptually, Im trying to make it so that when you click the action button it clears out the data in a cell. If I don't put anything in the value under the advanced options it doesn't do anything. So far the only thing I can do is pass a single space.

Edited, using a reference to an existing blank cell does not work
