HELP!!!!!!!!!!!

Hi - I am trying to complete a project for my Advanced Higher Computing project, that involves me using Assembly Code to compare 3 numbers, then redirect to where necessary. However, when the compiler tries to compile the program, it keeps throwing back an error "Undeclared Label: JL L1".

I am using the EMU8086 emulator. Here is my code below. Any help for a noob is appreciated. Thanks =D

[code]
#make_COM#

; COM file is loaded at CS:0100h
ORG 100h

PAGE 200,200
TITLE Compare 3 Numbers
.MODEL Small

.DATA
FIRST DW 123 ;Declares first variable as 123
SECOND DW 213 ;Declares second variable as 213
THIRD DW 312 ;Declares third variable as 312
ANSWER DW ? ;Declares answer variable unknown

.CODE
