I want to create a border...

Question

but it is not working!!!!!!! I want to create a border around a box. What I have done is create 2 separate transform groups one with the filled boxes and another with lines. The border works fine if it is just around one box in any position but when it is placed around a group of boxes it doesn't work! Consider the board a boardgame board... there have to be borders around the boxes so that the users can know where a square ends and begins spent all day on this today... didn't think that something so simple would be so difficult!! Thank you in advance for helping! Below is the code

Sorry the line:
subGroup.addChild(lineSquare);
should read:
blackLines.addChild(lineSquare);
