If you want to move the contents of the stack pointer into another register, you need
mov ax, sp
i.e. you shouldn't in this case be using the square brackets, which mean "calculate an effective address". I use tasm, not nasm, so there may be some differences; sorry if I'm misinforming you.
If you want to move the thing in a memory location pointed to by sp into another register, then I don't think
mov ax, [sp] is valid.
I think you should consider just doing
pop ax
push ax
which I think should achieve the same result.
Hope that helps...
