Gen Codebox Compiling Inputs Incorrectly

Hi I am trying to use gen codebox to do custom programatic routing of 64 inputs to 64 outputs.

When I save and my gen codebox compiles, in1 doesn't work, and the code output shows that in1 is being treated as a value of zero by the compiler:

In my gen codebox I have the line:

out10 = in1;

This shows up as the following in the code tab:

expr_2 = 0; 
... 
out10 = expr_2;

This seems like my code is simply being compiled wrong. How do I fix this?

All the other input -> output routing is working as expected.

Here is my complete gen patcher:

Here is my full gen codebox code:

out10 = in1;
out11 = in2;
out19 = in3;
out18 = in4;
out17 = in5;
out9 = in6;
out1 = in7;
out2 = in8;
out3 = in9;
out4 = in10;
out12 = in11;
out20 = in12;
out28 = in13;
out27 = in14;

out25 = in16;
