Adding to counter with 2 negated events?

[Dynamite]

Ok so here is my code:

>>"Player" is overlapping "Object1"
-Subtract 1 from Counter

>>X"Player" is overlapping "Object1" (NEGATE)
-Add 1 from Counter

Yeah that worked but then I added these:

 >>"Player" is overlapping "Object2"
-Subtract 1 from Counter

>>"Player" is overlapping "Object2"(NEGATE)
-Add 1 from Counter

The problem is simple but I can't seem to fix it. What happens is if the Player overlapps object 1 it subtracts to the counter but if it is not overlapping object 1 it Adds to the counter.

But I made the same thing with object 2 which stuffed it up.
See the player is overlapping object 1 but it is not overlapping object 2 which makes the counter add. How can I stop this without creating a ne counter for all the objects?

>>"Player" is overlapping "Object1"(NEGATE)
+ "Player" is overlapping "Object2"(NEGATE)
-Add 1 from Counter
