How do I change the position between two instances?

I am using the drag and drop behavior and when the instanced is dropped in another one I want that instances change its position but I don't know how to implement it. Could anyone help me with this?

Use the trick with families.

Create a family with just this one object. Then you will be able to refer two different instances of this object in one event. Like this:

I saw that you use a distance of 100 pixels for each one but in my case I will work with more than 2 instances. So I intend to register its positions in two local variables (positionX, positionY) and use them to define the place of each instance that I am changing.

Thanks, this solution worked very well.
