Hi, I'm doing that "Houdini isn't scary" beginner series with the donut. I'm at the point where he makes the particles bounce off the icing collision, them stick to it. Around 14:00

I can't get the sprinkle particles to bounce off or stick to the icing. I could swear I do exactly what he does.

Can someone tell me what I'm doing wrong? I'm not sure what I should share images of because I'm brand new to Houdini. Here's the main network though.

I hope somebody can help. Please ask if you want more screenshots of something.

Thanks
