Thank you, Chris. That worked.

PHP Code:

function onTimeout() {
  if(leftmousebuttonglobal) {
    with(TradeInventoryFloater) {
      this.x = mousescreenx;
      this.y = mousescreeny;
    }
    this.dragging = true;
    setTimer(0.05);
  }
  else {
    temp.target = TradeOfferScroll.globaltolocalcoord({mousescreenx,mousescreeny});
    if(temp.target[0] in  |0, 138|) { //TradeOfferScroll.width
      if(temp.target[1] in |0, 260|) { //TradeOfferScroll.height
        echo("Added to offer");
      }
    }
    else {
      echo("Destroyed");
    }
    this.dragging = false;
    System.destroyobject("TradeInventoryFloater");
    setTimer(0);
  }
}
