Basic question about hotspot and buttons
So I am just starting with storyline but I can't seem to get this figured out. So here is my basic question. I have 3 levels of layers on this slide. The base layer has various 2nd layers and from one of the 2nd layers I want to use the mouse to hover over various buttons to show different 3rd layers. However everytime the mouse moves off that button it goes back to the base layer and not to the appropriate 2nd layer. I just don't know what to add to make the image return to the appropriate 2nd layer and not to the base layer.
