Hello. I had a task to write a program which finds minimal elements in each matrix column. I kinda wrote program, but when i check results they are kinda different.

.model tiny
.code
.startup
                Org      100h
                Jmp Short Start
N Equ  2
M  Equ 3
Matrix DW 1, 7, 3   ; 2 elementi diapazonв [Min, Max]
DW 4, 5, 6   ; 3 elementi diapazonв [Min, Max]
Vector DW M Dup (?)
S Equ Type Matrix
Start:
Xor Bx, Bx
Mov Cx, M
Lea Di, Vector
Cols: Push      Cx
Mov Cx, N
Xor Si, Si
Xor Ax, Ax
Xor      Dx, Dx
Mov  Ax , Matrix[Bx][Si]
Rows:
 
   Cmp Matrix[Bx][Si], Ax
Jg False
Mov  Ax,  Matrix[Bx][Si]
 
False:
Add Si, S*M
Loop Rows
Mov [Di], Ax
Add Bx, S
Add Di, S
                Pop      Cx
Loop Cols
Xor Bx, Bx
Mov Cx, M
Print: Mov Ax, Vector[Bx]
Add Bx, S
Loop Print
          
.exit 0
end

Could someone point out or help me correct my mistakes?
