请看下面的程序，错误是计算无效有效地址，我刚才提到的那一行请告诉我为什么计算无效有效地址这里是程序

[org 0x100]
jmp start

array1: dw 10,15,20,25,30,35,40,45,50,55
array2: dw 15,10,20,35,40,30,55,50,25,45

start:  mov bx,0
    mov cx,0
loop:   mov ax,[array2+bx]
        cmp ax,[array1+cx]//here is the error invalid effective address calculation 
        jne NextElementOfArray1

NextElementOfArray2:    add bx,2
                        cmp bx,20       
            je end
                        mov cx,0
            jmp loop

NextElementOfArray1:    add cx,2        
                        cmp cx,20       
            je NextElementOfArray2   
            jmp loop
end:    mov ax,0x4c00
    int 0x21
