Dealing damage in an area with triggres

[Orphen_123]

im trying to make a spell that simply deals damage in an area of 500 around the caster. but when i try and deal the damage (using triggers) it doesnt work. it either damages every unti, including the caster(killing him) or damages no 1. can any1 help, wat triggers should i use

Pick every unitwithin range 500 of position of triggering unit matching (matching unit is an enemy of triggering player)
Loop actions:
Damage picked unit with damage 300....blah blah

 

[Orphen_123]

Unit Group - Pick every unit in (Units within 500.00 of (Position of (Casting unit)) matching (((Picked unit) belongs to an enemy of (Owner of (Casting unit))) Equal to True)) and do (Unit - Cause (Casting unit) to damage (Picked unit), dealing 500.00 damage of attack type Spells and damage type Normal).

every thing works but it deals damage to every unit within range. so kills the unit casting the spell

Shouldn't that be Matching unit instead of Picked unit?
