Error in defining Heterogeneous Regions with Meshmaker 1.5

Hi everybody,

I have a question about geometry definition in meshmaker. I tried to define a very simple layered material by using meshmaker 1.5, and I tried to define the layers by heterogeneous regions definition. Unfortunately, I encountered an error which the program did not read subdomains name for making geometry.
I would be grateful if you help me with this problem and let me which part should be modified in my inputs.
