ASM error in NASM

I am having an issue with this piece of code:

loop :              

    jmp loop        

times 510 -( $ - $$ ) db 0              
dw 0 xaa55

It is giving me an error saying:

boot.asm:6: error: comma expected after operand 1

I don't know what is causing this. I just started trying os developing, so don't expect me to know that much.

You need to remove the space after between the 0 and the x on line 6. 

loop :              

    jmp loop        

times 510 -( $ - $$ ) db 0              
dw 0xaa55

0x indicates a hexadecimal number, and so it cannot be split up with spaces.
