Help! Custom spell keeps looping

[X-Death]

I made a custom triggered spell utilizing the Channel ability. When the spell finishes, it starts again on its own. Why is this happening and how can I prevent it from happening?

 

[Fruit Forest]

We need your triggers to see (or map itself)

 

[X-Death]

You shouldn't need to see the triggers. This is a common problem with custom spells, I just don't remember how to fix it.

Then add event Generic unit is interrupting ability
Condition:
Ability being cast equal to The Channel
Do action:
Order unit to stop.

That event doesn't exist. Should I use the event "Finishes casting an ability" instead?

Finish that means full cast, but the channeling may be interrupted. (My version isn't english, you should find something that looks like stop casting or interrupting or something)

Event "Stops casting an ability" worked. Thanks!
