Drag & Drop Logic Cp7

I have 3 drop targets and I want to have the 3 drag sources be allowed on each one of them so:

Drop Target 1 can = Drag source 1 or Drag source 2 or Drag source 3

Drop Target 2 can = Drag source 1 or Drag source 2 or Drag source 3

Drop Target 3 can = Drag source 1 or Drag source 2 or Drag source 3

I have a series of numbers for ages and three of the people are the same age so I want them to be able to drop any of those ages on the drop target.

The problem is that I am not getting it to fire when "Auto Submit Correct Answers" I think because I have all the possibilities for the drop targets.

Can someone recommend a better solution for getting the event to fire?

Thank you.
