Hi Mike, take a close look at how Majik's surfaces are set up, notice how his upper surface is all one single surface and it's smooth in these areas here:



Now compare your upper object in those same areas:



Notice how your upper object is not smooth there - you've got sharp creases in those areas and that means that your upper object is not just a single surface, it's made up of multiple faces. That also means that the bottom edge is not just a single edge like it was for Majik's case, instead you've got a bunch of separate split up edges.

Surface blending is limited to only be able to connect a blend between 2 edges, so it helps if you form the upper piece that you are trying to blend to make it just one big smooth surface instead of fragmented into multiple pieces with sharp junctures between them.

Other than making the upper object modeled as one smooth surface the other way you can deal with segmented edges in Blend is to split up the bottom edge into segments as well so that you have matching pairs of segments. You can split an edge up into smaller edges by selecting it and using Edit > Trim and clicking the "Add trim points" button to place points at the spots where you want to cut the edge up.

Hope this helps!
