Hey all.  
I seem to get this error whenever I run my program.

-----------------------------------------------------------|  
ERROR

namePicker-cli.rb:58: syntax error, unexpected ‘{’, expecting kEND  
@names { |f| lines = f.readlines  
^  
namePicker-cli.rb:60: syntax error, unexpected ‘}’, expecting kEND  
-----------------------------------------------------------|  
What does this mean? Here is my code:

### LINE 58

```

Suggestions? Any?

Untested, but shouldn’t this be

```
 @names.each{ |f| lines =

```

f.readlines ### LINE 58  
lines.puts unless $. == selected.chomp  
}

Basically, you are defining a block for an instance variable here,  
but only methods can take blocks in Ruby. I assume you meant to call  
some iterator and forgot to include the method name.

Hope that helps.

If you’re not living on the edge,  
then you’re just wasting space.

This is fine and in that case you don’t need the block at all. You  
can just write to the file with:

@names.puts “…”
