Trigger Set-up Problems

Ok I want this trigger to Make special Effects on a Unit after It is Targeted by a Spell but im not sure how to set it up. I want it to be like
E) Unit - Is Target By a Spell
C) Spell = Frost Nova
A) Do special Effects

To bad that seems to easy >.< every thing has to be complicated.
If anyone knows a way to make this happen please tell me; Thanks.

Look in the Map Development Tutorials Forum. Coffein created a very nice tutorial on how to enhance spells with triggers.

Thanks that did help some, but he has this one trigger in the Conditions area that i can do for some reason

(Issued Order) Equal To Human Mountain King - Storm Bolt

I cannot find the Spell List any where to from all i can do is
Orderd(stop) and that wont help me i changed the "stop" to Undead Lich - Frost Nova but it didnt work..... Help would again be appriciated.

I figured it out..... I need to Use UMSWE wish i woulda know that 5 hours ago though...... woulda saved a lot of time. Thank you for directing onto the right path though.
