Range help (Custom Spells)

Anybody know how to get around the range problem with spells? IE when you use the unit is issued an order event for custom spells.

Any help would be most appreciated thanks.

I mostly use inferno as the dummy spell, and create Triggerer Custom units wich only work is to get removed and detected by a trigger

Events:
A unit spawns a Summoned Unit

Conditions
Unit type of (Summoned Unit) equal to Spell Triggerer

Actions
Set point = Position of Summoned Unit
Remove Summoned Unit from the game

And to get the caster unit I use Summoning Unit
