Drag n Drop with custom Feedback-overlays after each correct drop

Hey Captivate Community.

I am building a drag n drop but run into the same issue.

I want to build a drag n drop exercise where:

- you drag elements into an area that contains more than one dragged element eventually

- your dragged elements snap back when not dropped into correct target

- you advance to the next slide once, and only when, you dropped each element correctly.

- a feedback text (consisting of grouped objects, one textfield and one button) for each drag-element is shown after you drop that element correctly.

- Therefore I assigned an object action that shows that feedback text (group)

So far so good. What causes troubles is the last feature:

- Once you click the button inside that feedback group, however, instead of hiding the feedback text (what it is supposed to do), it advances to the next slide even though the exercise is not finished yet. I double checked: the button triggers the action "hide" (Feedback group).

I'm sure it's just a detail but I can not find it.

Thanks in adavance.
