Hi there,

I think you could use the Lua File System (http://keplerproject.github.com/luafilesystem/manual.html#reference) to accomplish this. Specifically, lfs.dir looks like it would enable you to count the number of entries in a directory.

Alternatively, you could have your code maintain of the number of shows that a person has made (starts at zero, every time they make a show it adds 1, every time they delete a show it subtracts 1, etc.), and you could then store that count in a file (so that it persists even when the app is closed).

Hope this helps.
