In this activity, students can pick one food to see the nutrition facts of the food.
I upload the nutrition facts as images in the GRAPH, and set the opacity of each to 0. So when the students pick one food (from the multiple choice), the opacity will turn to 1 (Slide 1).
On the preview, the images are still appear (even though just for a second).
BUT, when I only upload the image and set the opacity to 0, without CL connecting GRAPH and Multiple Choice, there images are clearly disappear (Slide 2).
Should I change the CL? How so?
Thank you in advance.
