<In what way does your code behave incorrectly? Include ALL error messages.>

```

my_array = [“raindrops”, :kettles, “whiskers”, :mittens, :packages]

Add your code below!

symbol_filter = lambda { |x| x.is_a? Symbol }

symbols = my_array.select(&symbol_filter)

<do not remove the three backticks above>

{ |my_array| my_array.is_a? Symbol}
examine this part of your code

You need parentheses around your lambda - ( lambda { block } )
