Stopping a series of images from appearing on a motion path
I am building a carousel in Storyline 360 and I'm having difficulty figuring out how to stop the motion path. I have added a group of 10 images (7 which are visible + 3 hidden) to a motion path that I can move left or right. When I click the right arrow I can reveal the 8th, 9th and 10th images - however I cannot stop it. If you continue to click the right arrow the images will eventually scroll off screen.
How do I stop the images from scrolling - or disable the right arrow button - after the last image appears on screen? I have tried a few different storyline tutorials but I haven't noticed this option anywhere.
I have included my file if you wish to see what I have done...
