For dividing string in lua you can use such function:
Code:
12345678910
> = string.sub("Hello Lua user", 7) -- from character 7 including 7 until the endLuauser
> = string.sub("Hello Lua user", 7, 9) -- from character 7 until and including 9Lua
> = string.sub("Hello Lua user", -8) -- 8 from the end until the endLuauser
> = string.sub("Hello Lua user", -8, 9) -- 8 from the end until 9 from the startLua
> = string.sub("Hello Lua user", -8, -6) -- 8 from the end until 6 from the endLua
