Pretty advanced Trigger Spell - Need help

OK the custom spell is a fire wall and is enhanced with triggers. This is what i have got so far:

Actions
Unit - Create 1 Firewall caster for (Owner of f_wall_caster) at f_wall_target facing (Facing of f_wall_caster) degrees
Set f_wall_caster2 = (Last created unit)
Special Effect - Create a special effect at (Position of f_wall_caster2) using Doodads\Cinematic\TownBurningFireEmitter\TownBurningFireEmitter.mdl
Wait 0.40 game-time seconds
Special Effect - Create a special effect at ((Position of f_wall_caster2) offset by (0.00, 20.00)) using Doodads\Cinematic\TownBurningFireEmitter\TownBurningFireEmitter.mdl

And here is my problem, I dont know how to create the effects(the fire) in the right line(by using offsets of course).

Anyone able to help me out?

Use - Angle of (facing angle of unit)

Wow..I need the offsets, so the line of fire is proportional to the facing of the caster..

If you were reading carefuly you would have seen that I already used that.

Anyone? :(

ofset is X-Y, so | by - (as i recall) now ofset it by say 30 iu nthe direction of the units facing, thencopy that and chanye the --- so that they move in a line, ajusting the | to make it so that tye are always the same sistance, think of it as a circle in a circle, witout ajustign the oouter circle, it is parralel to the inner one.

???

check my offset tutorial. thats the basics. use polar offsets, and count the small grid spaces from ur guy to the next flame in the line

By using what angle? I tried

Special Effect - Create a special effect at ((Position of f_wall_caster2) offset by 40.00 towards ((Facing of f_wall_caster2) - 90.00) degrees) using specialefect.mdl

and

Special Effect - Create a special effect at ((Position of f_wall_caster2) offset by 40.00 towards ((Facing of f_wall_caster2) + 90.00) degrees) using specialeffect.mdl


But that didn't seem to work

Get on irc and ill try and explain..
