Particle timer datapack

I'm having trouble getting my datapack to work. It's supposed to show particles on certain players every 10 minutes — for example:
Players with a “growth” effect should get portal particles,

Players with a “shrinking” effect should get squid ink particles,

And one special player emits soul particles.

I think I set it up correctly, but nothing is showing in-game. Here's the file — I'd really appreciate any help figuring out what's wrong!
