For the sweet life of me I cannot figure out what is wrong with my code. And since the solution does not give an answer only to nr. 1 then I can’t figure out this first part.

Here’s what I have

dogs <- dogs %>%
transmute(height_average_feet = (height_low_inches + height_high_inches)/2)/12,popularity_change_15_to_16 = rank_2016 - rank_2015)

I have the same issue ! It’s so frustrating.

You need one extra parenthesis before height_low_inches. Aside from that, it looks fine to me!
