You don't want to be putting split planes inside other split planes... If all you want to do is put one isolated plane, surrounded by another, just use the layer stack manager design -> layer stack manager to assign the whole plane to one net, and insert your split plane using place -> split plane. (this is safe, for as many non-overlapping islands as you want). If you want to put split planes inside other split planes, you need to be wrapping a C-shaped sausage of one plane around an island of another, and, if you care, deleting the closed bit of the sausage as the _very_ last thing you do - in the gerber editor if you can, or there's a risk that Protel will redraw the plane vias, and tie the planes together... This leads to much drilling out of vias, and unhappy prototypes :( I hope that helps a bit - if not, I'll try again with less beer tomorrow...
