a nil value (like must issues)

Reported by Bug Grabber:

1x sfbs-4.0.0.0\sfbs.lua:15: attempt to index local 'self' (a nil value)
sfbs-4.0.0.0\sfbs.lua:150: in function `OnEvent'
<string>:"*:OnEvent":1: in function <[string "*:OnEvent"]:1>

Locals:
self = nil
checkshown = <function> @ sfbs\sfbs.lua:19:
RegEvents = <function> @ sfbs\sfbs.lua:13:
Update = <function> @ sfbs\sfbs.lua:85:

I have tried to make the changes from "this" to "self", but something is not right, obviously. I am still learning how all this works.
I'm not the original author, but have been handed the reins. The addon is SleekFreeBagSlots (aka sfbs and FreeBagSlots). Any help will be much appreciated. If another author wants to see what I've tried doing, PM me and let me know how to send the current .lua I'm working with.

Thank you very much!
