I've been trying to guess where you might have intended to call your
message() function from - I suppose it would need to be called at the
end of load_file() ?
Anyway, it seems as if this will not work:

I am assuming that this function is called from the load callback? If
so, it seems likely that this test will always fail, since the
callback is triggered when the button is released. Therefore, at the
point at which this code runs, the button value will always be zero,
so you will always execute the clear_text() code path instead.
Is that perhaps what has been happening?
