Please help with "parfor" not working!!! Don't know what's wrong!

Hello,

I've got 4 nested for loops, with the outside loop as the parfor. I know a little bit about parfor sliced variables, so I got a different function with 2 nested loops (total of 2 loops) to work. But this version with 4 total loops doesn't work. Below is the modified code (for simplicity). I thought I'd taken care of the variable classifications and assignments, but

it's still giving me the error "Parfor cannot be run because of the way temp_up is used."

=========== CODE ===============

%Initialize Variables;

result_up = zeros( length( Z ), length( A ), length( B ), length( C ) );

temp_up = zeros( length( A ), length( B ), length( C ) );

%Start Parallel Loop

parfor Z_COUNT = 1 : length( Z )

      Z_CURRENT = Z( Z_COUNT );

      for A_COUNT = 1 : length( A )

          some_var_up = some_function1( Z_CURRENT, A( A_COUNT ) );

          for B_COUNT= 1 : length( B)

              for C_COUNT = 1 : length( C)

                  return_up = some_function2( some_var, B( B_COUNT ), C( C_COUNT );

                  temp_up( A, B, C) = return_up;

              end

          end

      end

      result_up( Z_COUNT, :, :, : ) = temp_up;

end

====== END CODE ======

I've replaced all of the code with Z, A, B, C, etc for simplicity. For the Love of God, someone please help me with this!

Ah......

Got it fixed.

I just had to move the "temp_up" variable from outside of the parfor loop, to just inside it so that each instance of the parfor loop can create the variable.
