How do I make the jump animation work?

I know, I posted again, late too, but can you help me?

I fixed my Sonic movement in my game but the jump animation doesn't work. Please help me fix it...

Create a parent event "Platform is on the floor" and move events 5-8 to it as sub-events.

I actually admit I have no idea how sub-events work, so I would never have done that, so thanks, again..!
