[Trigger] Decreases armor per hit

[AlwaysAndForever]

I found this map, so I edited it but I got 2 problems
1. The special effect above the tower takes a long time to remove
2. The reduced number will not be gone

And how can I put 3 towers into the trigger since I don't understand hashtable
So if I have 3 towers the first tower will decreased 1 armor per hit, second tower 2 third tower 3
Is there anyway to use other variables(integer/real or other thing) instead of hashtable?!
Can I use only 2 trigger 1 base on A unit is attacked other base on A unit Takes damage?!
