Help with TD

[Aaahn]

I really need help with my TD. I want to do so towers can combine with each other by casting an ability. But it doesnt work! No matter wich ability i uses, the casting tower is removed! and that happens even if the combine tower triggers is off.
+rep to the one who helps me.

1. Change casting unit to triggering unit.
2. Replace triggering unit and remove the target instead.
