strange bow thingy

[excaliber7388]

Okay, If a person is in a level with baddies that shoot stones, arrows, etc, the player's arrows reduce, I've looked through my own NPCs and I have no idea where this came from. Also, if you use this weapon, two arrows are taken away (this is my replacement for the bow, because i thought that it might be the problem, but, wrong. What could be doing this? (Note, this is not a problem with bombs, just arrows)
My bow:

NPC Code:

---

if(actionserverside){

  if(strequals(#p(0),darts)){

    playerdarts=playerdarts-1;

//   ^ ^I know the right way to do this, I was just expirementing a bit

  }

}

//#CLIENTSIDE

if(weaponfired){

  triggeraction 0,0,serverside,*Bow,darts;

   if(playerdarts>0){

     setani shoot,;

       if(playerdir==0){

         shootarrow up;

       }

      if(playerdir==2){

        shootarrow down;

      }

      if(playerdir==1){

        shootarrow left;

      }

      if(playerdir==3){

        shootarrow right;

      }

  }

}
