Dumb String Array Question

[zallus-k]

NPC Code:

---

function destroyBoxes() {

  if(strtofloat(#I(clientr.boxes,0))>=1 && mousedown && leftmousebutton && !noclose) {

    for(this.i=1;this.i<=strtofloat(#I(clientr.boxes,0  ));this.i++) {

      if(mousescreenx in |strtofloat(#I(clientr.boxes,this.i*2-1))+189,strtofloat(#I(clientr.boxes,this.i*2-1))+198| && mousescreeny in |strtofloat(#I(clientr.boxes,this.i*2))+3,strtoflo  at(#I(clientr.boxes,this.i*2))+16|) {

        set noclose;

        deletestring clientr.boxes,strtofloat(#I(clientr.boxes,this.i*2-1));

        deletestring clientr.boxes,strtofloat(#I(clientr.boxes,this.i*2-1));

        replacestring clientr.boxes,0,#v(strtofloat(#I(clientr.boxes,0))-1);

        unset noclose;

      }

    }

  }

}

Can anyone suggest what this code needs, besides cleaning up? Currently, it'll only work (to delete a box object) if there is something at the x,y coordinates specified, and even then it'll only delete the end box. Anyone have an idea? Also, the strings are a necessity, as the script is multi-level.
