Hey korbaach, I'm not messaging because of something new lol. I figured everything out (thanks again by the way), there's just one small thing... It's the "markerYear" object. When I push the up button ("btnList" object), the "markerYear" object is visible (like it should be), but, when I push the down button ("btnList"), it either goes invisible, or maybe, it's sticking to 2015 (which is the first year on the list now instead of 2010... I switched it). Do you know what the problem might be? I don't get it... I followed your steps, the two "btnList" buttons are actually one object, just like in your example, I also set the "markerYear" image point to 0, 0. So, I don't know if it's a "markerYear" problem or a problem with the "btnList" object...
When pushed up (it is visible):
When pushed down (it either goes invisible, or it may be sticking to 2015 (which is the first year instead of 2010... I switched it)):
