Unable to make cut (with surface) due to unhappy surface knit

I'm having a very frusturating time. This is my first project in Solidworks since college and it seems a lot has changed since SW 2007. I'm trying to build tweeter mounts for my vehicle so I have a left housing and a right housing.

 

My attempted steps were:

1. Sketch start and end faces

2. Sketch guide curves

3. Lofted boss with sketches

4. Surface offset to the interior (so I can hollow it out)

5. Trim extra off of surface offsets

6. Knit surfaces

7. Cut with surface

 

I completed the left housing with very little trouble so I have bee. Now working on the right one, perorming the same steps, I can't seem to satisfy the surface offset -> trim -> knit -> cut with surface. After I believe I have knitted my surface correctly, the 'cut with surface' tool is greyed out which I assume means I don't have any surface to satisfy it.

 

The other strange thing about the knit tool: In my left model (the one that works like I wanted), if I attempt to edit my knit surface, it will default to knitting "surface-trim-1" although the original function I selected face1 face2 and face3. If I rebuild allowing it to change to surfacetrim1, it gives me an error "cannot knit surface to itself.
