Need help installing a dynamic layer slider

Hi there,

I’m trying to make a layer slider for my homepage on http://www.amberidentity.com so that previous blog posts will rotate in the slider. I made a new slider and clicked on “configure post options”, but I’m not sure where to go from here. Could I get some help on the next steps? I want the slider to constantly be scrolling through random posts. I’m also not adept at coding at all so if there’s an easy way to do this, I’d really appreciate it. Thank you!

Best,
Amber
