LUA Error in Dungeon

[cnewman777]

Before this error occured, I was having this problem occasionally...

http://zygorguides.com/forum/showthr...2292-Lua-Error

So as per your instructions, I followed these steps:
1. exit WoW
2. go to the WoW/Interface/Addons folder and delete the ZygorGuidesViewer folder
3. go to the WoW/WTF/Account/<accountname>/SavedVariables folder and delete the Zygor files in there
4. run the desktop client and install a fresh copy of the guides

Next I go back into WoW, I'm in a dungeon and the following error kept occuring:

13x ZygorGuidesViewer\Item-ProcScore.lua:129: attempt to index field '?' (a nil value)
ZygorGuidesViewer\Item-ProcScore.lua:129: in function `ParseEffect'

Try disabling all other addons to see if you get this error in dungeons with only Zygor running. Something is trying to run when you are in combat and we don't have LibActionButton-1.0 as part of our libraries so that's a different addon in the error call. Guessing another addon is triggering the error but Zygor is the one catching it and reporting it.
