Implementation of selection sort on Assembly language using library Irvine

Question

I am implementing Selection Sort on Assembly language using irvine32.inc and I have some how implemented it to the best of my capability can you check my Selection Sort function I tried to debug and it is giving me an extra zero after very array index so the last two sorted elements are not assigning themselves in the array.

Include irvine32.inc

.data
    a3 dword 20,12,10,15,2,62,45,100,300
    temp dword ?

.code
swap proc,val1:PTR dword,val2:PTR dword
    mov eax,0
    mov esi,val1
    mov edi,val2
    mov eax,[esi]
    xchg eax,[edi]
    mov [esi],eax
    ret
swap endp
Selection_Sort proc,A: PTR DWORD,n:DWORD
Local step:DWORD,min_index:DWORD,i:DWORD
    mov eax,0
    mov step,eax
    forin:
        call Display
        mov eax,step
        mov min_index,eax
        inc eax
        mov i,eax
        fori:
            mov esi,[A]
            mov edi,[A]
            imul ebx,i,type A
            add esi,ebx
            imul ebx,min_index,type A
            add edi,ebx

            mov eax,[edi]
            mov ebx,[esi]

            cmp ebx,eax
