I am getting an access violation error in MASM when part of my sorting procedure is ran on a $7$ row by $9$ column table named NUMS. Can you spot where I went wrong or any other potential issues with my procedure syntax? Thank you.

sorting PROC ; sort each row of NUMS table separately

mov ecx, $7$

mov esi, OFFSET NUMS

row$\_$loop:

push ecx

mov ecx, $9$

column$\_$loop:

mov ax$,[$esi$]$

cmp ax$,[$esi$+2]$

jl swap

add si$,2$

loop column$\_$loop

swap:

mov bx$,[$esi$+2]$

mov $[$esi$+2],$ ax x

mov $[$esi$],$ bx

add esi, $2$ Exception Unhandled

I know there are calls to other procedures, but I$\text{'}$m trying to figure out this issue with the sorting before messing with any of those first.
