palette cycle

I have made tiles from a scratch and I ripped the palettes from newfirst and such but now when I want to use a palette cycle the colors that are supposed to cycle turn black instead and do nothing . What have I done wrong?(I have copied the cycle from a newfisrt palette(the lava)).

Did you turn the Interpolated fading rule on in the rules menu? Palette Cycling won't work without it checked.

I have but I already know how they work
You have to copy palettes in the lower spots in a level palette so they can cycle(bad explain).
