I meant to click on :-) at the end of the second to last tutorial video in JS and the DOM, but accidentally clicked :-(.

Is it possible for me to change a sad face rating to a smiley face rating for a video tutorial that I have already rated? I am absolutely loving Guil Hernandez's course on "JavaScript and the DOM," including every last lesson in it! He explains things really patiently and thoroughly, and is helping me to improve my understanding of how to manipulate the DOM using JavaScript phenomenally much! In fact, I think that he is really helping me to learn this really cool new JavaScript skill! Yet, it's getting late, I'm a little tired, and I was mindlessly scrolling down at the same time that I was clicking on the emoji icon to indicate my reaction to his awesome video lecture, and accidentally clicked on the sad face, when I meant to click on the smiley face. Could someone please help me to fix that?
