THE PROGRAM NEEDS TO SUM ARRAY AND PRINT BUT IT CRASHES PRINT NOTHING

          .data
          array1 byte 10,20,30,40,50

         .code
         main proc
         mov eax , 0
         mov eCX , 5
         mov bx , 0

         l1:
           ADD AL , array1[bx]   I; IF I USE BYTE PTR AND AX INSTEAD OF AL IT GIVES ERROR
           inc bx
           inc bx    ; IF I INCREMENT BX 1 TIME THEN ALSO CRASH
         loop l1

         MOVZX EAX,AL
         printf("%d\n" , EAX)

         ret
         main endp
         end main
