Is it possible to do this with an array?

A movieClip has the name pE1, when the user clicks the movieClip the event handler catches the event.currentTarget.name (pE1) then I want to use this string to tell a child class(_model) to add an object(engine: object) of that same name(pE1) to an array within that child class.

I’ve been trying things like:

var obP:Engine =_model.allEnginesArray[getChildByName(e.currentTarget.name)];
_model.examineEngineList.push(obP);

Any thoughts?
