The function createRulesPanel wont works for me, im trying for a days to make this works, but im failed, so i coming here and ask @ all if you can help me a little...

The connection to the rules.txt file its successfull established but instead to draw the window, the function try to print the rules.txt out ti the outputbox chat... like this:

* Rules not yet downloaded. Press F9 again.
GTI Rules failed to load. The rules file is not configured correctly.
[string "Art 1° - Não praticar Power Gaming: Mínimo (10H) Máximo(24H..."]:1: '=' expected near '1'

Thx in advance and sorry for my bad english...

loadstring loads Lua code from a string into a function than you can call (to execute the loaded code). Looking at the loadstring error message, it does not appear that you're putting code into that, but rather a string of text, not code.

You have two options:

Either change line 65 to

memo = guiCreateMemo(241, 24, 450, 437, "Bem vindo/a ao RPG City Reallife. Use o menu á esquerda para navegar pela documentação do servidor.\n\nRegras do Servidor:\n\n"..rules, false, window)

and remove line 28 through 34 (the safer option, since you remove the ability for arbitrary code execution in your script)

Or the second option, is to change the rules.txt file to contain valid code which this script expects. It appears to expect a table named theRules with a string of rules under the key "English", so your rules.txt should be

local theRules = {
  ["English"] = "Art 1° - Não praticar Power Gaming: Mínimo (10H) Máximo(24H ..."
}

and it should load correctly. However, this is less safe, since it can allow someone with access to editing rules.txt to insert malicious code into the file, which is then executed on through clients' Lua interpreters.

@MrTasty

I am very grateful for your help, unfortunately I could not solve the problem in this way. I tried everything possible, at the end its was just an "unfinished string" and still didn't give me the rules.txt file on my memo GUI. Then I decided to use the xml variant. This was successful, i thank you again for everything.
