Oh duh, it's a logic issue. Ok,here's the lowdown on what's happening in your example (still tired, bear with me ).

1) check for global foo

if not foo then...

2) if global foo doesn't exist, create a local foo

local foo = "foo"

3) after declaring the end of the if statement, local foo is destroyed. Translated as per the compiler:

foo = NIL

4) attempt to create text

text = foo..bar

5) ERROR - a global foo still hasn't been created. And since the local was destroyed in stage 3, foo still remains as NIL

Also, I realize after looking back that the function would have to go before the scripts (which is always a good practice to maintain, for the record), but you posted the fix already.
