I need to write a code in 8086 emulator where a user gives an input from 0 to 9. If the value is below 3, 'Good morning!' is printed. If the value is greater or equal to 4 and less than 6 (just 4 and 5, basically), 'Good afternoon!' is printed. If the value is greater or equal to 8, 'Good night!' is printed. For the values 3, 6 and 7, the system does nothing.

However, in my case, I am getting an output for these three values as well. What are the issues with my code?

.MODEL SMALL
.STACK 100H
.DATA  
    STRING1 DB "Enter number:$"
    STRING2 DB "Good morning!$"
    STRING3 DB "Good afternoon!$"  
    STRING4 DB "Good night!$"
.CODE
 MAIN PROC
    
    MOV AX , @DATA
    MOV DS , AX
    LEA DX , STRING1
    MOV AH , 9
    INT 21h
    
    MOV AH , 1
    INT 21h
    SUB AL , 30h
    
    CMP AL , 3
    JL good_morning
    
    CMP AL , 6
    JL next_check
    
    CMP AL , 8
    JGE good_night
    
 good_morning:
    LEA DX , STRING2
    MOV AH , 9
    INT 21h
    JMP exit_label
    
 next_check:
    CMP AL , 4
    JGE good_afternoon
    
    good_afternoon:
    LEA DX , STRING3
    MOV AH , 9
    INT 21h
    JMP exit_label
    
 good_night:
    LEA DX , STRING4
    MOV AH , 9
    INT 21h
    JMP exit_label    
    
    exit_label:
    MOV AX , 4C00H
    INT 21h
    
    
 MAIN ENDP
