Function in CUDA?

I'm working with an FDTD problema and to get a better performance I'm programming in CUDA. What am I doing wrong?

This my code:

  using BenchmarkTools
  using CUDA
  CUDA.@allowscalar(true)
  
  tamaño::Int32 = 200 
  epsilon = CuArray{Float32}(undef,tamaño)
  
  function Cond_Front()
  
      CUDA.@sync CUDA.@allowscalar  for mm in 1:1:tamaño
          if (mm <= 100)
              @inbounds epsilon[mm] = 1.0
          else
              @inbounds epsilon[mm] = 9.0
          end
      end
      return #nothing
  end
  
  
  function bench_gpu1!()
     CUDA.@sync begin
          @cuda Cond_Front()
      end
  end
  
  # MEDICION DEL TIEMPO DE EJECUCION
  @btime bench_gpu1!()

Thanks

This is the error I get :

IDs have conflicting values ('i32 4' from globals with 'i32 2' from start)
