I'm doing something very obvious, bu cannot see it, aint I? Here's the code:

You know, if you get a warning or an error message with a line number, and ask about it, don't just post a blob of code, also indicate which line the warning is about. Now you've already gotten two replies, and both replies guess a different line where the error might be. At least one of the answers is about the wrong line.

Number your lines, or place a comment in the code "this is line 21". A little courtesy towards the people answering is welcome.
