My attached « test_gallery.hype.zip » is in french but it doesn't matter for the demo.
I created a simple gallery of geometric figures animation (some sort of slideshow left to right direction).
I have a timeline animation (Galerie) for that purpose.
I want to trigger the plus button within each figure along the Galerie timeline.
So, I also have individual timelines for each figure (rectangle, cercle, ellipse) for that.
Those animations are working fine individually, but I cannot figure the sequence of actions to make it work altogether.
After several tries with no avail, I prefer to ask more talented people for help.
