The last exercise in the "Quosures" section of https://ijlyttle.shinyapps.io/tidyeval/#section-writing-functions-that-use-tidyeval tells me to uncomment an expression that assigns "birth_year" to input_name and then change a function call, presumably so that the variable input_name is passed into filter_sym_value. However, doing this results in a tibble with zero rows rather than the same tibble produced by the original code. Have I misunderstood the instructions?
