Can't find the fault in my code

["Fred M. Sloniker" <fredsloniker@...>]

I'm working on writing a program to help me make 'to-do' lists for complicated builds in Minecraft, and there's some simple error in the code, I'm sure. Unfortunately, the error I'm getting is "'lua: temp.lua:74: 'do' expected near '<eof>'", which, given what's actually at line 74, suggests the fault is somewhere else. Can anyone help? I pasted the code to http://pastebin.com/mLNhdiK4 .
