Blending a cylinder to a free form surface

Today I'm teaching myself the blend command. Right now I cant seem to get any results. I did watch a video tutorial a few days back on blending and now I cant find it.

Here's the deal. I was just trying to get a curved fillet and not a straight one. I can use loft just fine between surfaces. I did join the the opening (lines) on the free form object.

I also did the sweep around the opening on the free form to make it larger.

Do the two objects have to have a similar profile to be able to join with blend or do I use another command? I think at one time I had it that way and it didn't work.

I don't know, I may just be missing a step.

The image is showing lofting.
