I am new to ZPL Programming. Can someone tell me whats wrong with me ZPL program.

I have to design the following label: https://i.stack.imgur.com/60UHl.png
But up till now I have achieved this: https://i.stack.imgur.com/xL285.png

But when I add another grid I lost the last barcode: https://i.stack.imgur.com/q1vb4.png

Is there something wrong with my code or can someone help me appending the upper two grids.

Here's my code:
