So I've got a structure, Structure A, that is invulnerable. There are 2 cannons defending Structure A, Cannon A and B. How would I go about making a trigger that makes Structure A vulnerable if Cannon A and B are destroyed? Thanks.

Store both of your cannons for the base in an array, and then have something akin to this.

Action: Any Unit Dies
Conditions:
(Cannon[1] is alive) == false
(Cannon[2] is alive) == false

Actions:
Unit - Make (StructureA) Vulnerable

Doesn't seem to be working, Structure A just stays invulnerable. .^

Let me take a look at the map.

For this you will need a Variable named say "CannonsKilled". If your working with multiple lanes you might want a variable for each lane like Cannon(Top) Cannon(Bottom) Cannon(Middle) ect... An array would work fine for that.

There are other ways I am sure, but I would write it like this...

    Events
        Unit - Any Unit dies
    Conditions
        (Triggering unit) == Cannon
    Actions
        Variable - Modify CannonsKilled: + 1
        General - If (Conditions) then do (Actions) else do (Actions)
            If
                CannonsKilled == 2
            Then
                Unit - Make Structure A Vulnerable
            Else
                General - Wait (9001.0 / 0.0) Real Time seconds

Ok, I'll give that a go first.

Edit: Thanks, works fine now.
