(Assembly) Exception thrown error? (with STOSD instruction)

I'm writing a procedure that fills an (2d) array with random integers. The array address is to be passed through a stack to the fillArray procedure.

For some reason, when I run the code, I get an exception thrown error: "Exception thrown at 0x00403687 in Project.exe: 0xC0000005: Access violation writing location 0x004036A7." I can't figure out exactly what's causing this. I'm guessing it has something to do with the way I'm passing the array address, since the error message disappears once I comment out "mov edi, [ebp+8]", but I can't figure out how it's wrong.

fillArray PROC arrAdd
    mov ebx, 0
    push ebp
    mov ebp, esp
    push eax
    mov ecx, (ROWS*COLS)
    mov edi, [ebp+8]
    cld
    fill:
        call Randomize
        mov eax, MAX + 1
        call RandomRange
        add eax, 10
        STOSD
        mov ax, numArray[ebx]
        inc ebx
        call writeInt
    loop fill
    pop eax
    pop ebp
    ret
fillArray endP

main PROC
push OFFSET numArray
call fillArray
