Ahh, I see. You can't just paste the name and click the button. You have to start typing the name (or paste it and then wait) and then it'll give you a pulldown of matches. Then you select from the matches and then add the plant. Try that and let me know how it goes. Consider that it's a search engine, not a place to type whatever you like. It's matching your text with the actual plants in the database.
