Code:
dot = string.find (contents[1], [[.]])

doesn't work. Neither does
Code:
dot = string.find (contents[1], ".")

Does anyone know why this happens or how to do this?

no, contents[i] is right. I'm trying to find "." in the array contents where i is the entry number. i = 1 So it reads from the first entry of contents. I'm not wrong there

Easy, by default find does pattern matching, so . matches any character.

(I don't know how many threads I have answered with links to PIL already... just read it! - I didn't know Lua 3 weeks ago either ;))

Btw, what you want is "%."
