Player SUBMIT button acts diff than "Submit Interaction" trigger

Hi E-Learning Heroes! I need a bit of help.

I've created a drag-and-drop activity, and when you use the SUBMIT button in the Player, it behaves exactly the way I want it to:

• It scores the interaction as correct or incorrect, and
• It changes the states of the drag items to "drag correct" or "drag incorrect" as appropriate

However, I need to remove the SUBMIT button from the Player** so I created a new button with a "Submit Interaction" trigger, and this is what it does:

• It scores the interaction as correct or incorrect, but
• It DOES NOT change the states of the drag items

Have I made an error in how I set up this trigger? Is there a simple solution?

Or, if the button+trigger is simply programmed to behave differently than the Player SUBMIT button, is there a workaround? I'm willing to add a bunch of variables and extra triggers to make this work, but I'm not sure where to start.

I've attached a file containing the drag-and-drop question. It has both the original Player SUBMIT button (that works, but I don't want to use it) and the custom button+trigger (that I'd like to use, but it doesn't work)

Thanks for any help!

** I've been using the SUBMIT button as an EXIT button in several related activities, so I'd like to keep it that way for consistency, if at all possible.
