"Attempt to index field" error

I was doing just some simple gear additions to sets when I started getting this. http://imgur.com/a/gGi3Q

At first it was just on my cor lua that I had modified. Then I said screw it, and downloaded a fresh cor lua that mote made and got the same error.  Then the same error started happening when I would switch to other jobs with luas I hadn't changed like blu. This is far beyond my troubleshooting abilities. This is the offending lua. http://pastebin.com/AggkNckh

Forgot to mention, I loaded the offending cor.lua and switched to it again, the error popped back up when I tried to load that lua.

I'm also getting the same error when I try to equip gear from the command line doing //gs equip.

here is one error i found and in your setup it wont work because this is the only time you use equipSet anywhere in your lua

equipSet = set_combine(equipSet,{waist="Hachirin-no-Obi"})

I put that line in there from someone else's lua to get hachi obi to equip when voidstormII was on. Not sure how that got in but it did somehow. Taking that out appears to have fixed it. Much appreciation.
