I'm trying to write a test class, but I keep getting this error message.  Here's my code:

 I've scoured the code to find the (apparent) unmatched curly bracket, with no joy, so I'm probably doing something else wrong which is messing with the compiler.  If I put a right curly bracket on line 82, as would be obvious, it matches up with the bracket at the start of the class, the message becomes "unexpected token: for" which makes sense as it would be appearing after the bracket ending the class definition.  Can anyone offer suggestions about what is wrong and how to fix it?

Thanks in advance.
