Issue with Drag and Drop activity
So, I have a course with a custom drag and drop interaction, which in fact doesn't make use of the preset "send" button nor the preset feedback squares (which don't match the aesthetic of the course which is pretty complex). Feedbacks are in separate slides and the submit button makes use of particular variables that are set to turn to 1 when it is dropped correctly and jump to the particular feedback when done (when all options' variables are 1, it gives you the correct feedback, and when one of them is NOT 1, it goes to the incorrect feedback). It works really well and there's no issue in its functionality.
But after talking with the client, they asked if we could make the user to answer or at least drag the objects to submit. Currently, if you don't drag nothing and click on submit, it gives you the pertaining feedback until you see the correct answer. Is there a way to have a pop up or something saying that you have to complete the activity before submitting? (Kinda like what storyline has that says you need to at least drag or answer one option to submit). I thought of using some variables to state that the user has or has not dragged an item to one of the targets (either correctly or incorrectly) but I'm getting confused because I already use variables and it might render the activity useless. Any ideas?
(I can explain with further detail how the activity works if needed)
