Loft/Panel Frame are giving errors

I am getting errors when trying to offset and use loft or Lunchbox Panel Frame.

I have done a bunch of different things but I am not sure what the issue is.

My end goal is to merge the planar surfaces of the sides of the bird feeder, but I can’t get them to become one piece without some kind of error. The current error is invalid breb

What version of Rhino do you have?

I’ve tried and replaced the FMerge component with the one from the latest version of Rhino 7 and it works fine.

I am using Rhino 7. I am still getting an invalid Brep from the component you added.

I’m having this issue elsewhere in the file now too. I really don’t know what I’m doing wrong. I have only been working with Grasshopper a couple of weeks and I’m very new to CAD so it proably something simple I don’t know yet.
