Solve the following python programming problem given the following code:
def _populate_volume_state_table() : 
    '
        Initialize volume state table  with transitions for ``create_volume``,
        ``attach_volume``, ``detach_volume``, ``delete_volume`` operations.
        ' 
    O = VolumeOperations 
    S = VolumeStates 
    table = pmap () 
    def add_flow(operation, start, transient, end, sets_attach, unsets_attach) : 
        '
            Helper to add expected volume states for given operation.
            ' 
        return table.set (operation, VolumeStateFlow (start_state = start, transient_state = transient, end_state = end, sets_attach = sets_attach, unsets_attach = unsets_attach)) 
table = add_flow (O.CREATE, S.EMPTY, S.CREATING, S.AVAILABLE, False, False) 
    table = add_flow (O.ATTACH, S.AVAILABLE, S.ATTACHING, S.IN_USE, True, False) 
    table = add_flow (O.DETACH, table.IN_USE, S.DETACHING, S.AVAILABLE, False, True) 
    table = add_flow (O.DESTROY, S.AVAILABLE, S.DELETING, S.EMPTY, False, False) 
    return table 

    
    

    Fix the buggy line: table = add_flow (O.DETACH, table.IN_USE, S.DETACHING, S.AVAILABLE, False, True)
