Hello,

I have a problem with my own written program.
I always get the message:" Tute:1: attempt to index ? (a nil value) " but I can´t find a mistake.

Here is the pastebin program link: http://pastebin.com/UxSXS3Ra

Thanks for your help

so, from what i can see, there is nothing wrong :/ what i'd do in this situation is just remove it, then run the code, and then to attempt to put it in afterwards.

I don't think that this is a verson error as i could use turtle.select back in tekkit classic.

If the program you show is Tute (shouldn't in be turtle?), then it means that turtle is actually nil. (strange)

Are you sure you are using a turtle? Or are you just coding on a normal pc?

are you running on a turtle? the turtle API is only available on turtles.

The program name has nothing to do with the turtle api.

It does when the first line of the posted script attempts to index into the turtle table, and the error calls that impossible. Creator was suggesting tutedutsch had the wrong file, as it's not often people make the mistake of trying to run turtle code on a non-turtle.

How so it does? I am really not getting how a program name and an api can have anything to do with each other, other than if the api name was renamed to "tute" in this case.

Error:

Tute:1: attempt to index ? (a nil value)

Line 1 of posted script:

turtle.select(1)

Therefore, if the posted script is "Tute", then "turtle" is nil... which turned out to be exactly the case.
