This wont select the next variable in thiso.rights.
thiso.rights = Stick,Unstick,Jail,Stealth
can someone help me get this to work?

PHP Code:

function onKeyPressed(code, key, scancode) {
  for (temp.i = 0; temp.i < thiso.rights.size(); temp.i ++) {
    //[ 219
    //] 221
    //\ = 220,\,43
    if (code == 219) {
      //[
      if (this.selected - 1 => thiso.rights[0]) {
        this.selectedid = temp.i;
        this.selected = thiso.rights[(@this.selectedid - 1)];
        UpdateText(this.selected);
      }
    }
    if (code == 220) {
      //\
      if (this.selected + 1 =< thiso.rights.size() - 1) {
        this.selectedid = temp.i;
        this.selected = thiso.rights[(@this.selectedid + 1)];
        UpdateText(this.selected);
      }
    }
  }
}
