Embedded MatLab Function Errors

I'm trying to simulate a very simple scenario. The model starts with a constant block that inputs 55 into an embedded function that simply adds the value 10 to the constant, then outputs it into a display block.

Here is the list from the console:

Warning: The model 'untitled' does not have continuous states, hence Simulink
is using the solver 'VariableStepDiscrete' instead of solver 'ode45'. You can
disable this diagnostic by explicitly specifying a discrete solver in the
solver tab of the Configuration Parameters dialog, or by setting the 'Automatic
solver parameter selection' diagnostic to 'none' in the Diagnostics tab of the
Configuration Parameters dialog

Code generation failed Attempt to execute SCRIPT union as a function:
/Users/dazgti/Documents/MATLAB/union.m

I have a script named union.m, but I have no idea why its trying to execute it.

 function y = fcn(u)
%#codegen

x = u + 10;

y = x;

In configuration parameters, just choose a discrete solver
