time expires?

Im trying to have events with timer expires but they never seem to work? am I doing somthing wrong?

event- time- timer(p2 timer) expires
action- add points to leaderboard

the event doesnt work, I know thats not the exact action I just didnt wanna type the whole thing out, I tried action display text msg dgjdgjdgfhg and it didnt work, so somthing is wrong with the event, I just cant figure out what.
p.s. does any1 have explosion sounds? like booom ! the closest I could find was human building blowing up. I want a big boom kinda a firery sound, explosion a bomb would make. Also whats a good idea to make inviso not overpowerd/ but not underpowerd. I have a 6v6 map, and I want a unit to be invisable, like a shade always inviso. However its to powerfull like that, if I let people buy gem, its a little to underpowerd (I would think) and dust of apperance wouldnt be quit good enough, cuz you would need to use it alot. So far Im leaning towards gem hopefully it wont make the invisable guy useless

One of the things I've found is that some events and conditions just don't work like they're supposed to. So the best way is to work around them with things you know that work.

Example:

Trigger 1
-Event
:Something
-Conditions
:something
-Actions
:Start Timer1 (with so many secs)
:Turn on TimerEnd1

TimerEnd1
-Event
:Timer1 expires
-Conditions:
[none]
-Actions
:Something

well you know that doesn't work, so instead try:

Trigger 1
-Event
:Something
-Conditions
:something
-Actions
:Start [Timer1] (with so many secs)
:Turn on TimerEnd1

TimerEnd1
-Event
:Every (number timer starts with) seconds
-Condition
None
-Actions
:Turn [this trigger] off
:Destroy [Timer1]
:All the other stuff

We know the Every ## seconds works, it'll still show the timer (even though it doesn't really count) for the players, and it'll destroy the timer at exactly 0:00:00,and it'll turn itself off right away so it'll do the stuff, but never execute again after it's done.
