Problem with Helper triggers

[Master0fFaster]

The character has a hidden meter that builds up on hit and falls over time. The idea is to summon a helper that indicates the level of the meter when a hit gets the opponent past certain thresholds. This helper is more like a message that shows up momentarily then vanishes.

However, I can't seem to be able to make the helper show up only once. I can either make it appear only when the variable hits the exact numbers I am looking for, or it is called constantly once it goes over said number.

I'm also trying to make sure that the Helper is called if said value falls under the threshold then gets past it again.

You essentially need to track what was the last thing the helper did. Can be a variable. Or if it's really a helper you can use different states. So that it only shows for instance the level 1 notification if it was in level 0 before.
