Setting a new runtime class variables gives Null reference

Question

I have a class:

 class aPart
 {
     var partName : String;
     var partDescription : String;
     var partIcon : Texture2D;
     var partIconRect : Rect;
 }

 public var partList = new Array();

During runtime, i need to make a new part and add it to an array of parts i have:

 function storeNewPart(partToStore : String)
 {
     var newPart : aPart;
     newPart.partName = partToStore; //null reference here, why?
     newPart.partIcon = Resources.Load(partToStore);
     partList.Add(newPart);
     ArrangeParts();
 }

I am an artist turned scripter, and have been stumped by this for several hours now. I can not find any good solution around this. What is the correct way to create a new part on the fly and add it to my partList?? Thank you for taking a look :)

You didn't initialize newPart, you only declared it; it's null (hence the error).

 var newPart = new aPart();

Thanks Eric, worked perfectly. I apologize for the silly question, still learning new things daily as I push my scripting abilities. I promise i searched! Apparently I didn't know what I was looking for.
