Solved Mobs don't spawn on "every (time)" event

[CrimZ0N]

Basically what I tried was

every minute:
----spawn 1 zombie at {invisible.Spawners.Zombie::*}

Can they even spawn, if so, how do I make it so that it spawns at a variable?
I also have this, if it makes sense

on place of barrier:
----if name of tool is "&bInvisible &2Zombie &bSpawner":
--------cancel event
--------remove 1 barrier from player named "&bInvisible &2Zombie &bSpawner"
--------set {invisible.Spawners.Zombie::%location of event-block} to true

I'm bad please help ;w;

loop it

every 1 minute:
 loop {invisible.Spawners.Zombie::*}:
  spawn 1 zombie at loop-value
