Accessible drag and drop issue

Dear community,

I am using Storyline 360, and am having issues changing the state of an image when it is dragged and dropped onto another image.

I am using triggers to accomplish this task as the out-of-the-box drag and drop templates are not WCAG accessible.

https://community.articulate.com/discussions/articulate-storyline/build-an-accessible-drag-and-drop-interaction-in-storyline?

I followed the above tutorial, but it did not include grouped objects, and my triggers look identical.

My goal is to change the state of an image grouped with a text box to "drop correct" or "drop incorrect" (which look identical) depending on where the dropped item lands.

To do this I am applying triggers to the group that I am dragging, and commanding them to change the state of the image they are grouped with when the drop interaction is completed.

My issue is -- on completion of the drop interaction, the state of the grouped image is not changed to "drop correct" or "drop incorrect"; instead it takes the state of "Normal". This means that my "submit" button -- which tests for the states of the grouped images -- always returns incorrect.

Additionally you will note that I have triggers to complete the drag and drop interaction via a click to select and a click to deposit interaction. This trigger also does not work; when I click to deposit a selected drag group on a drop image the grouped image maintains its state of "selected" as opposed to changing states to "drop correct" or "drop incorrect" despite my triggers mandating otherwise.

Unfortunately I cannot change the state of a group of objects and instead must change the state of its components. I believe this is the root of my problems.

Any help or guidance would be much appreciated.
