Continue button when clicked after correct response does not lead to the next slide

Hi,

Thank you for the quick responses!

Unfortunately, the content is a client file and i cannot share the file with you. But I have checked the link shared for custom drag and drop. All I want is the user to drop the items in the correct targets and click continue once they get the feedback (correct or incorrect layer) to move to the next slide. The interaction works fine and shows the correct and incorrect layer but when i add a new slide, and a trigger to the continue button to move to the next slide, i can move to the next slide but i don't see the feedback. 

Please see the attached screenshot from the link shared with me. Over here, once I drop the items in the boxes, how do I ensure I can go to the next slide by clicking Continue? 

Also Walt Hamilton mentioned adding a trigger to hide the correct layer or incorrect layer, could you explain what that trigger is about and what could be the statement for that trigger?

Thank you for any response you may have!

Thanks and regards,

Susmita
