Clear an Enumeration value

I have an enumeration that is set to a specific status (decline in this case) and I would like to clear the value. I don't want to set a different enum value but I would like to change it back to its originat state (before an enum had been selected). I tried to use a change object action and set the value to empty or Null but that doesn't do the trick.

This is easy, just do a change action on the object and set the value of the enum to 'empty' without the quotations. I've just double checked this and it does work fine.
