Dota like Trigger Help?

So, I'm trying to work on a file on my main map, which is to many it where when 6 towers fall, this vault becomes Vulnerable, but I can't understand the triggers, I barely understand Integers & how they work aside the Variable stuff. can anyone explain to me, How I can set it up where when the towers fall, the building becomes attack-able? I'd appreciate it.

I'm assuming you're using preplaced units and don't expect them to ever come back after dying.

• Untitled Trigger 001
  • Events
    • Unit - A unit Dies
  • Conditions
    • (Tower 0000 <gen> is dead) Equal to True
    • (Tower 0001 <gen> is dead) Equal to True
    • (Tower 0002 <gen> is dead) Equal to True
    • (Tower 0003 <gen> is dead) Equal to True
    • (Tower 0004 <gen> is dead) Equal to True
    • (Tower 0005 <gen> is dead) Equal to True
  • Actions
    • Unit - Make Town Hall 0001 <gen> Vulnerable

There are better ways to accomplish this but I tried to maximize simplicity.
