Having a hard time understanding sliders
Just when I thought I understood how they work to make a parallax effect (after this week's ELH challenge) I can't get my idea to work!
I'm trying to get one image to come in from the left and one to come in from the right, controlled by one slider.
I'm running into two issues:
1. The sliders are not moving.
2. How do you know how long to make your track and what numbers to put into the start/end/initial/step fields? I've tried lots of combinations and they don't seem to affect the sliders at all.
File is attached.
