        Set UnitsGroup = (Units within 1000.00 of (Position of (Target unit of ability being cast)) matching (((Matching unit) is alive) Equal to True))
        Set NumberUnits = (Number of units in UnitsGroup)

Target unit of ability being cast, no such thing, with the event "A unit FINISHES...", or it might, but that would be middle of the map then... Two options, change the event or add another trigger which stores the point in a variable when he starts the effect of that ability. Then use the point variable later on, in the "finishes"-trigger.
