Show layer if activity is completed successfully
I have a drag and drop exercise where the user has to fill in the blanks with 5 words. The user knows he/she has completed the exercise correctly because only the correct words can be dragged onto the correct blanks.
That is why I don't want the user to click on a "submit" button only to receive an information that he/she already knows. I'd rather have a layer appear with the message "Well done!" and a customized "next" button that allows the user to move onto the next slide.
In other words, I need a trigger like "show layer if/once activity is completed successfully".
Can it be done? Thanks.
