So we have to guess what the error is and where it happens?

Full code and full error message, please.

Just in case:
You seem to be missing two } at the end of the function that you posted.

laoadam:
Compile failed。

It was bound to fail. That's not a complete program. You can't compile snippets.

I expect it told you what the failure was and exactly where it occurred. So you have a lot more information than we have. Good luck.
