I can't write my data to the data file , Why?

Your indentation is messed up, so it's really difficult (...or impossible) to guess what your code actually looks like. But from what's been shared, nothing is written to the file, because you only try writing to the file if there's an error, but AFTER a break statement, which means nothing would ever be written, regardless of error states.

When I delete it still doesnt work
