label inconsitently redefined NASM

问题

i have been following a YouTube tutorial on how to make an operating system, as well as experimenting with writing assembly code my self. I use NASM to turn my assembly files into executable binaries, and use qemu to run them.

-=-=-=-=-=

boot.asm

[org 0x7c00]

mov [BOOT_DISK], dl

mov bp, 0x7c00
mov sp, bp

mov bx, tst
call pst
call readisk

%include 'print.asm'
%include 'diskread.asm'

jmp $
times 510-($-$$) db 0
db 0x55, 0xaa

-=-=-=-=-=

diskread.asm

PROGRAM_SPAVE equ 0x7e00

readisk:
    mov bx, PROGRAM_SPACE
    mov al, 4
    mov dl, [BOOT_DISK]
    mov ch, 0x00
    mov dh, 0x00
    mov cl, 0x02

    int 0x13
    
    jc diskreadfail

    ret

BOOT_DISK:
    db 0

diskreaderr:
    db 'Failed to read the disk!',0

diskreadfail:
    mov dx, diskreaderr
    %include 'print.asm'
    call printstring
    
    jmp $

-=-=-=-=-=

print.asm

printstring:    
    mov ah, 0x0e
    .looper:
    cmp [bx], byte 0
    je .exit
        mov al, [bx]
        int 0x10
        inc bx
        jmp .looper
    .exit:
    ret
teststring:
    db 'Hello, World!',0

I get a few errors while trying to convert. I am not sure how i 'define the same label more than once to different values.'
