The thing is, that to check the ID and to read the string we don't need to use array and using global stuff for this is perfectly fine. Cause as soon as I read data (into global var or string), I save it into the array (in original code). I use list to save text's title, id, max page amount and each page (one by one), but I've ripped everything from this example to make it simplier. So it has nothing to do with the problem. Which part exactly you can't understand, I'll try to explain it more with some deeper details.
