HELP - Answer not being accepted, what am I missing?

For some reason, the answer I type in isn’t being accepted.

students <- students %>%
mutate(gender = str_sub(gender_age, 1))
head(student)

This is the solution given by CodeAcadmy (which includes the following question)

Capture1

Even when i edit the solution to exclude age and copy and paste it, I’m still getting an error message.

What am I missing?

Hi,
I wonder if it’s because your variable is stated twice at the beginning: students <- students %>% Maybe you aren’t supposed to do that…?
