Re: Help with error #2007 Parameter hitTestObject must be non-null.

You can then replace the following:

1. if(hitTestObject(target))
2. {
3.   visible = false;
4.   target.alpha = 1;
5.   Object(parent).match();                             
6. }
7. 
   

with this:

1. if(hitTestObject(evt.target))
2. {
3.   visible = false;
4.   evt.target.alpha = 1;
5.   Object(parent).match();                             
6. }

I didn't understand why you've kept target as a member variable in that case though. I do not have the full context here, probably you have missed the assignment to target before the drop event. Just double check. In that case, the change I mentioned above will not be required.
