It works, but doesn't do what you wanted it to. Select into an item directly, such as

select ic_id
  into :block.display_item_name
  from cd_details
  where price = 599;

P.S. Alternatively, in your code, you miss the following:

  select ...

  :block.display_item_name := num;
end;

What makes you think that code doesn't work?
Of course you should probably be fetching the value into a display item rather than a local variable. There's not a lot of point selecting a value if you do nothing with it.

Yes, you do sound really stupid. You wouldn't if you read what I posted in my first answer to your question, which contains both how to select directly into an item, as well as how to put variable's value into an item.
