Need immmediate help with program (basic C++ stuff)

[YevGenius]

Hello,
I've writing a function to find the three largest integers in a 3rd dimensional array which has #0 to 9 stored exclusively. However, I keep getting the same highest # (usually 9) stored in max_store[]. I have tried everything, and I don't know where to go next. If some one could please offer me some help, I'd really appreciate it. I need this asap. Thank you so much.

void find_max(int fun[ROW][COL][LAYER]) {
   
   int num, r, c, l, k;
   int max=0;
   int max_store[3]={-1};

   for (num=0; num < 3; num++) {
      for (r=0; r < ROW; r++) {
         for (c=0; c < COL; c++) {
            for (l=0; l < LAYER; l++) {
               for (k=0; k < 3; k++) {                         
                  if (max < fun[r][c][l] && max_store[k] != max)
                     max = fun[r][c][l];
               }
                   
            }
            
         }  
          
      }
      
      max_store[num] = max; 
      max = 0;
     
      
   }
