You are indeed mismatching curly brackets and missing a comma, but your command is far more broken than that. You can't have an equipment slot that just has 'Dear Ryan, I luv you!'. For a start, a string like that, it must be enclosed in quotation marks. Secondly, that's not an item, that's just random text. What are you trying to achieve with that text? I can't imagine it's too hard to fix up. You need to be more detailed with your request though.
Can someone help me balance the { things in this command, thanks Im being quick, so yeabye thanks
