When do you close the stream?

after writing, viewing then reading the text file

[KevinWorkman]

Are you sure? That error seems to suggest otherwise. I can't really read unformatted code though, so the best I can do is suggest you step through this with a debugger, or at least add some print statements to figure out what's going on.

You can edit your original post to enclose the code in [code] tags [/code].
That way we might actually be able to read it.

i've already fixed it

[Tolls]

Can you provide a run through that gives the error?
That is what the user inputs?
I can see at least one route through where the stream used by 'br' is closed and the loop goes back round with a closed reader (user selects '2' then '1').
It's hard to tell because your indentation is all over the place.
