Hi there @ipmipest I see some spelling errors in the above code

• line 3, the arguments to the function should be (state = null, action). You misspelled null here

• line 4, your switch statement should switch over the action type, not the state. The correct switch should be: switch(action.type)

• Also on line 5, your case statement should be a variable that should have been declared above as stated by the instructor to reduce errors. You should have something like:

  const BOOK_SELECTED = 'BOOK_SELECTED'
  ...
  export function(state = null, action) {
  switch(action.type) {
   case BOOK_SELECTED:
      return action.payload;
  }
  return state
  }

  Keep up the good work!
