so I have been declaring my instances inside the package

public var projectDetail:ProjectDetail = new ProjectDetail();

which is fine but I don’t really want to create the instance automatically when the class is created and I do not need to make them public but the problem is if I create in in a function

public function createDetail() {

var projectDetail:ProjectDetail = new ProjectDetail();  
stage.addChild(projectDetail);

}

public function deleteDetail() {

stage.removeChild(projectDetail);

}

I get his error, 1120: Access of undefined property projectDetail.

because the variable only exists in its own scope, it there an alternative technique rather than use public variables all the time?
