Trigger problem on spell help!

Heyas, im trying to make a spell off blizzard.. which basically doesn't require channeling.. the way i did it was to create a dummy unit and cast a spell..the triggering spell is based off earthquake.. i could of used silence or anything else with an AE.. but this is how my trigger looks like
E
Unit cast a spell
C
Spell being cast equal to hail storm
A
Create dummy unit at position of casting unit
add 20 second expiration timer on last created unit
give last created unit hail storm effect
order last unit to archmage blizzard target point of ability being cast

but here's the problem..the effect only last for 1 wave then it just stops.. i even set the waves to 10 and still only casts it once.. any ideas on what i'm doing wrong?

First of all, the conditions added below event doesnt stop the trigger from executing if they are false, you must add a "IF THEN ELSE" instead.

2: Lol dont go "..." all the time its annoyign to read :D

3: What i usually do when using hidden casters is having them created with the abillity from start. Try creating the unit from start, and then just move it there, cast ability, then move away.

One thing you should remember is making the hidden unit without attack, so it doesnt stop abilities to attack. Another thing you should add is the "locust" ability (makes it invulnerable and unselectable) and the "bugger" model (invisible).

So my guess is that something goes wrong in adding the ability or similar; havign the caster unit created from start is one idea to test.

This wud be so much easier to figure out if it didnt cast blizzard at all; its weird that it casts one wave like that. You sure you are editign the correct skill when settign 10 waves?

What the hell do you mean by
Of course they stop the trigger from working if they are false.


And they were casting blizzard so the problem is not with the adding of the ability.

It is something else causing the dummy units to try another strategy or perhaps the blizzard skill has only 1 wave somehow.

Dummy units should have worker classification and Aloc

("Aloc" is the same as "locust")

Maybe there's something wrong with blizzard. When I was trying to use blizzard (for something comepletely unrelated to this), I discovered that it was somehow different from other spells, that it wasn't properly channeled, but more like continiously recast... Anyway, I cannot be sure of this, but it is a possiblity that the dummy caser has problems when casting because the blizzard is not like other spells.

yea the dummy caster is classified as a peasant, invisible and has locust. All my settings are correct, i set it to 10 waves and it's still a no go =\
