Hello Wanjyun,

I will give you a little hint, check this event.preventDefault()

Try apply this event on the line 19 and check what happens.

If you want the answer or if it helps you, let me know =D

It actually looks like you've completed the challenge.

Except that in addition to adding the right code, there are some extra stray symbols and a few lines have been combined with the comments that precede them. I would think this was a lack of formatting, but I also see your code is properly formatted (perhaps by the "get help" button).

So look it over again, remove stray symbols (like "**$" and several "**"), and check that the code lines are not mixed up with the comments. You might just start the challenge over and (carefully) put in the same answers (1 new line and one word change).
