[Solved] Simple GUI Trigger Enhanced Spell

[Hermit]

EDIT: The ability seems to be working now.
I'm making an ability called Freezing Flood. It's based on Priestess of the Moon's Starfall. The ability has only one level and it's supposed to damage enemy buildings and slow nearby enemy ground unit's attack rate and movement speed. Since I barely have any experience in using triggers, please tell me if there is anything wrong with the triggers below (are there any leaks), and how can I improve it.

Frost Nova might be one of those spells that do not work for global caster dummies, similar to Chain Lightning. Have you tried to temporarily create a dummy unit for every enumerated unit?

Thanks for the reply, I edited my post above, since It looks like it works now.
