I’m sorry, but your instructions do not make any sense to me. I have tried to follow them, but I am unable to get the slider to work at all. As far as I can see I have followed all your instructions, but no slider appears on my pages.
I have created 2 new post pages, with featured images of the correct size.
I have set the slider options to 2 sliders
I have entered the page ids in the available boxes (post=200 & post=202)
Is there something else that I have to do to activate the slider and control where it appears?
