Having trouble with deathcheck...

I have this "attack" spell that's works well, except it's having trouble killing the monster.

mob/proc/Blast1(mob/M as mob) //removed most of the animation code...
    if(usr.mp>=5)
        var/damage=10*usr.level
        M.hp -= damage
        usr.mp-=5
        npcdeathcheck(M)
    else
        usr<<"<B>You don't have enough MP !</B>"



mob/proc
    npcdeathcheck(mob/P as mob, mob/M as mob)
        if (M.hp <= 0)
            P << "You have killed the [M]!"
            P.exp += M.expreward
            endbattle(P)
            del (M)
        else
            npcattack1(P, M)


Now, after casting the spell, it's shows some errors such as:
runtime error: Cannot read null.hp.
proc name: npcdeathcheck

Any ideas ?
THX.

Make sure the NPC has HP.

Make sure you provide both arguments for your death checker.
Like this:

npcdeathcheck(usr,M)


That should fix it.

In response to Cinnom
It works now.
Thx for your help.
