Okay I NEEED help right here!

So in this game https://flowlab.io/game/view/1319321, in the levels, select code then click the code bar. I have made an animation that will start when I press one key then when I press the next key, the second key will appear, and so on. The problem is, the animation will show only one key even if I press 100 keys. I also want the animation to not show anything when I press five keys. So for you to understand I have a video. https://www.loom.com/share/4d786457ee774df4acd5a1bf751fcb92 THANKS!

Because the previous animation is still playing, and you need to stop “stay on last frame”.
