AS2: Hjemmelavet klasse anvender anden hjemmelavet klasse?

Hej eksperter,

Er det muligt at anvende instanser af en hjemmelavet klasse i en anden hjemmelavet klasse?
Eksempelvis melder følgende fejl:

// Throw is custom class
class Graph {

    // ...

public function Draw(throw:Throw, startT:Number, endT:Number, quality:Number):Void {
        for (var i:Number = startT; i <= endT; i += 1/quality) {
            trace(throw.GetX(i));
        }
        return;
    }

    // ...

}


Fejl:


**Error** C:\Documents and Settings\Toke\Skrivebord\physics_throw\Graph.as, Line 25: Parameter name expected
    public function Draw(throw:Throw, startT:Number, endT:Number, quality:Number):Void {

    trace(throw.GetX(i));
