Drag and Drop with Scrolling Panel

Hello!

I am trying to do a drag and drop type of game. The objects that are to be dragged are located within the scrolling panel, while the drop boxes are outside the scrolling panel. It works perfectly when the scrolling panel is not there, using drop triggers. But once I do it with the scrolling panel the triggers stop working and I can no longer drag the objects. Can anyone help?

I attached the document. One of the slides is the drag and drop with the scrolling panel, and the other is without the scrolling panel.
